13 We report on renewing the undergraduate course about synoptic meteorology and weather

14 forecasting at Wageningen University (The Netherlands) to meet the current-day requirements

15 of operational forecasters. Weather strongly affects human activities through its impact on

16 transportation, energy demand planning and personal safety, especially in the case of weather

17 extremes. Numerical weather prediction models (NWP) have developed rapidly in recent dec-

18 ades, with reasonably high scores, even on the regional scale. The amount of available NWP

19 model output has sharply increased. Hence, the role and value of the operational weather fore-

20 caster has evolved into the role of information selector, data quality manager, storyteller, and

21 product developer for specific customers. To support this evolution, we need new academic

22 training methods and tools at the bachelor’s level. Here, we present a renewed education strat-

23 egy for our weather forecasting class, called Atmospheric Practical, including redefined learn-

24 ing outcomes, student activities, and assessments. In addition to teaching the interpretation of

st 25 weather maps, we underline the need for 21 century skills like dealing with open data, data

26 handling, and data analysis. These skills are taught using Jupyter Python notebooks as the

27 leading analysis tool. Moreover, we introduce assignments about communication skills and

28 forecast product development as we aim to benefit from the internationalization of the class-

29 room. Finally, we share the teaching material presented in this paper for the benefit of the

30 community.

31 Capsule

32 The role of operational weather forecasters has changed in recent decades, which means that

33 the new academic training in operational synoptic meteorology given at the BSc level must

34 address new topics, skills and infrastructure.

37 Weather forecasting is critical not only for social activities for the general public but also for

38 transportation, energy supply, water management, agriculture, and many other crucial infra-

39 structures and business decisions. Weather forecasts have become increasingly more accurate

40 in recent decades due to improved numerical weather prediction (NWP) systems as a result of

41 advances in understanding physical processes, data assimilation techniques and computing ca-

42 pacity (Bauer et al. 2015).

43 With these advances, the role of the operational forecaster has changed. Nowadays, the

44 output of multiple NWP models is freely available at a high temporal frequency, and they

45 cover the continental-scale dynamics for the medium range (3-7 days), and the mesoscale dy-

46 namics for the short range (up to 48 h). Also, observations from satellites, radar systems and

47 routine and crowdsourced near-surface weather stations are readily available. In addition, the

48 userbase of weather forecasts has diversified, requiring tailor-made forecasts for a wide range

49 of applications. As a result, the forecaster’s tasks have increasingly shifted from adapting the

50 NWP results for local conditions, towards data (model and observations) treatment, critical

51 data selection and storytelling for stakeholders. Educating the upcoming generation of

52 weather forecasters should consider the evolution occurring in the field, which motivated us

53 to revise the Atmospheric Practical course at Wageningen University (WU). Also, student

54 mobility and the diversity in the academic education landscape has strengthened, resulting in

55 students with variable prior knowledge. Previously, most of our students were Dutch and all

56 had a uniform prior knowledge from a common study program. Nowadays, the students who

57 enroll in our program have diverse geographical, cultural and educational backgrounds. Alt-

58 hough it may initially pose some challenges, this diversity also offers an opportunity for deep-

59 ening the course (Apple et al., 2014).

60 The Atmospheric Practical course teaches the fundament and practice of operational

62 opment of the field. We mainly address the introduction of an intake questionnaire, the inter-

63 national classroom, a new student activity to set up a forecast product, the implementation of

64 a modern scientific program language for data analysis, and the deeper attention needed for

65 communicating a weather forecast.

66

67 2. Positioning of the Atmospheric Practical course in the curriculum

68 The Atmospheric Practical is an optional course offered in the 3-year BSc program Soil, Wa-

69 ter, Atmosphere, which combines courses in the three disciplines with special attention to in-

70 terfaces at the land surface and vegetation. Students taking the course need two 6-ECTS at-

71 mospheric introduction courses (each with a workload of 168 hours): “Introduction Atmos-

72 phere” that uses an in-house made course reader and “Meteorology and Climate” based on

73 Wallace and Hobbs (2006). These courses deal with basic atmospheric physics and chemistry

74 covering thermodynamics, radiation, atmospheric dynamics, and boundary layers. Both

75 courses discuss basic weather forecasting, such as interpretation of synoptic observations and

76 radio soundings, and data-assimilation, as well as the concept of deterministic chaos and its

77 consequences. Didactically, the courses combine classroom lectures with pen-and-paper exer-

78 cises and computer-based assignments, mostly addressing the lower cognitive levels of

79 Bloom’s taxonomy (Anderson and Bloom 2001) regarding understanding, recognizing and in-

80 terpreting atmospheric processes. Finally, both courses include a number of weather briefings

81 by a from DTN Weather (Data Transmission Network, formerly MeteoGroup).

82 After two years, students specialize in one discipline offered in the BSc program. Typi-

83 cally, 25-40 students follow the Atmospheric Practical for their specialization. The course in-

84 troduces the forecasting cycle, which includes the process of obtaining observed weather data

85 and model outcomes to compile a forecast for different end-users (section 3).

87 First, we summarize the course history and then go on to compare the forecasting cycle be-

88 tween the 1980s and the 2020s. Finally, we address the renewed course learning outcomes,

89 structure and student assessment methods.

90 In the previous version of the course, the interpretation of surface and upper air observa-

91 tions and the NWP model output were key. The selected case studies had a national or West-

92 ern European focus, and the exercises involved a lot of manual work (often paper exercises on

93 printed weather maps) or were performed with a variety of outdated software packages. Also,

94 the NWP model datasets were limited to coarse resolutions of >25 km. Some exercises fo-

95 cused on spatiotemporal scales exceeding the characteristic time scales of synoptic meteorol-

96 ogy, e.g., exercises about the physical climatology of the whole globe. For student assess-

97 ments, there was limited discrimination between students, and a number of crucial subjects

98 such as communicating weather forecasts were absent. Nevertheless, the original set up

99 served its purpose for 15 years and was highly appreciated by students who graded the course

100 with a 4.3 out of 5 for the past six years.

101

102 a. Course content: Forecasting cycle

103 The forecasting cycle, which is the backbone of the course, has changed substantially over

104 the years. The forecasting cycle contains the following steps (Inness and Dorling 2013):

105 1. Collecting observations.

106 2. Using collected observations to specify the initial conditions for the forecast.

107 3. Using a model to extrapolate the state of the atmosphere in the future.

108 4. Experienced forecasters assessing the output of the model.

109 5. Producing forecasts for customers.

110 Figure 1a depicts a typical forecast cycle in the 1980s, when the short-term forecast was 5

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 111 made using synoptic observations. Only a limited number of global models (ECMWF, GFS,

112 JMA) were available and they were characterized by relatively coarse grid spacings (~50 km)

113 and lacked information on the mesoscale. Mesoscale meteorological models such as MM5

114 (Dudhia et al. 2002), WRF (Powers et al. 2017), HARMONIE (Bengtsson et al. 2017) and

115 COSMO (Doms and Baldauf 2013) did not exist. After a consistency check of the short-range

116 NWP model forecast with observations, operational actively modified the fore-

117 cast by “interpolating” the NWP output to local scales to account for the effects of unresolved

118 lakes, mountains, soils and land use. The medium-range forecasts were formulated mostly

119 qualitative. Finally, the forecast was verified against observations and lessons were learnt for

120 further model development.

121 Nowadays, the spatiotemporal detail of observations has increased enormously, which bet-

122 ter facilitates regional analysis, and even local (~1 km) nowcasting is possible (Figure 1b).

123 Additionally, dense networks of personal weather stations are available via websites such as

124 www.wunderground.com, www.netatmo.com/weathermap, https://pressurenet.io/ and

125 https://wow.metoffice.gov.uk/. Despite their relatively low accuracy and unknown siting,

126 these personal weather stations can offer local weather information about areas where official

127 observations are relatively scarce (Napoly et al. 2018, Hintz et al. 2019, De Vos et al. 2020,

128 Mandement and Caumont 2020). Also, a wealth of output from global and regional NWP

129 models is available with output up to 1 hour temporal and ~1 km horizontal spatial resolution.

130 Hence, the value that an operational forecaster can add to the forecast by accounting for local

131 conditions has decreased. Simultaneously, ensemble forecasting has matured and quantifies

132 the model uncertainty. This development now allows for local and regional weather forecasts

133 and warnings, while these were issued on the national level in the past. This advancement pro-

134 vides the meteorologist with the new task of assessing NWP uncertainty and translating it into

135 a meaningful forecast for end users.

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 136 The end user perspective to forecasts has changed as well. In the past, forecast communica-

137 tion occurred in relatively general statements that fit with the spatiotemporal scale that could

138 be resolved. Nowadays, many customer services, like precision agriculture, energy com-

139 panies, festival organizers as well as road and rail management agencies require targeted fore-

140 casts for their fields. Thus, forecast communication has become more important than in the

141 past (Pandya et al. 2009, Eden 2011). Customers want to know what consequences the fore-

142 casted weather could have for their operations and services. We will explain how these evolv-

143 ing aspects in the forecasting cycle are addressed in the course learning outcomes and student

144 assessments. Thereby we want to emphasize that the changes we made to the course are im-

145 plemented in consultation with representatives of the private meteorology sector, including

146 the senior forecaster from DTN. With their advice we could adjust the course to fit the needs

147 asked for graduates in meteorology.

148 b. Learning outcomes

149 Learning outcomes are crucial for the course delineation since they help to determine the cog-

150 nitive level as well as the student activities and assessments. In this third-year course, the

151 learning outcomes address the higher cognitive levels according to Bloom’s taxonomy (An-

152 derson and Bloom 2001), such as analyze and evaluate, along with the lower cognitive levels

153 on identifying and explaining. Taking into account the forecasting cycle, after successful com-

154 pletion of the Atmospheric Practical course students are expected to be able to:

155  Identify and recognize the different types of meteorological data and how frequently

156 these are available;

157  Modify, analyze and interpret different types of meteorological data;

158  Explain and discuss the relation between several atmospheric quantities varying in

159 space and time;

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 160  Monitor, observe and analyze the weather situation, and perform a professional fore-

161 cast of weather parameters using real-time or historical data;

162  Communicate a weather forecast for different customer groups and media;

163  Discriminate and evaluate the research performed at the various research facilities of-

164 fering meteorological services, education and data abroad;

165  Appraise career perspectives, research activities, meteorological disseminated data and

166 services provided by operational and research institutes abroad.

167 Table 1 summarizes the learning outcomes and the student activities that lead to the fulfilment

168 of the learning outcomes. Obviously, the students are exposed to a variety of teaching meth-

169 ods and activities, which will be elaborated on in the next section.

170

171 c. Course structure

172 For scheduling reasons, the course entails three consecutive weeks of full-day classes consist-

173 ing of 36 practical exercises (called modules, Table 2) and subsequently, one week where stu-

174 dents participate in an excursion abroad. Each week has a specific theme and the course

175 evolves from a relatively basic level towards higher learning outcomes.

176 Each module starts with a bit of theory from the course reader consisting of selected texts,

177 internet pages or book chapters that should take students about an hour to read. The course

178 reader is included in the supplementary material (S3). The course emphasizes the practical ap-

179 proach which enables students to digest the course material, since many individuals learn

180 most effectively by using concrete examples (Roebber 2005). As such, each module continues

181 with a practical assignment in which students actively diagnose and interpret weather obser-

182 vations or NWP model output using Python Notebooks (see section 4vii, and supplementary

183 material S4) or the MIDAS meteorological workstation (introduced below).

184 The first week’s theme concerns “Weather observations and models”. The course begins

8

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 185 with (re)introducing the basic synoptic plotting system, which is subsequently used to make a

186 coherent surface weather picture at the national and European scale, including front detection.

187 Students learn about the routinely available meteorological observations (surface and aerolog-

188 ical observations), their time frequency, and how they are exchanged between meteorological

189 services. Successful integration of observations with models and theory assists students to bet-

190 ter understand physical processes in the atmosphere (Etherton et al. 2011). Also, students

191 learn to visualize observations and model output in the MIDAS meteorological workstation

192 provided by DTN. MIDAS was chosen because of the long-lasting collaboration with DTN,

193 that started as a spin-off company of WU in the 1980s. In addition, students work with NWP

194 model output to learn about spatial resolution and the related consequences for a weather fore-

195 cast. This first week’s theme is finalized with a practical test (more details below under As-

196 sessment).

197 The second week focuses on the theme “Weather analysis”, which includes the interpreta-

198 tion of the spatiotemporal observations into a coherent understanding of synoptic and

199 mesoscale weather. First, radio sounding observations are studied to investigate convective

200 indices such as CAPE, CIN, and the Boyden index. Second, weather radar observations and

201 their limitations are discussed. Subsequently, the course treats satellite observations in the IR

202 and VIS ranges, and the RGB enhancement of images from METEOSAT/SEVIRI and

203 MetOp/AVHRR. The theme is completed with atmospheric dynamic concepts such as diver-

204 gence, vorticity, thickness and advection to improve the students’ understanding of the day-

205 to-day weather.

206 The third week focuses on “Weather forecasting”, where students practice making weather

207 forecasts (building upon preceding knowledge and tools) and present weather briefings for a

208 geographical area experiencing interesting weather (section 4vi). Moreover, students develop

209 meteorological products for specific customer groups based on scientific literature and from

9

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 210 direct NWP output (section 4v). For example, students are asked to develop a forecast for

211 clear air turbulence based on relevant model parameters from NWP output. As such, students

212 learn that the job of a forecaster has broadened and now includes forecast product develop-

213 ment. Yarger et al. (2000) reported that such forecasting exercises may lead to pronounced

214 improvement of long-term knowledge retention. Finally, the last day of the course is focused

215 on communicating weather forecasts (more details below under innovations).

216

217 d. Student Assessment

218 Student assessment consists of five different aspects. The first theme “Weather observa-

219 tions and models” is assessed with an individual closed book practical test that counts for 20%

220 of the final grade. The second assessment consists of a weather briefing preparation. Students

221 are divided into groups of two and given four hours to prepare a PowerPoint file with 10

222 slides. In this file, groups have to forecast the current weather for the Netherlands and the

223 outlook for the coming three days, applying the knowledge gained throughout the course. The

224 PowerPoint is evaluated via a rubric (Table S1) and counts for 20% of the final grade.

225 In theme “Weather forecasting”, students need to present a weather briefing (section 4vii).

226 The same rubric (Table S1) is used as in week 2, but now the students need to show their

227 presentation skills. Overall, this element counts for 30% of the final grade.

228 The fourth assessment element is the forecast product development (section 4v) and

229 counts for 10% of the final grade. Students are graded based on a rubric (Table S2) that sum-

230 marizes the requirements of the forecast product. The final assessment item is a student report

231 about the excursion abroad (20%), which we will not elaborate on here.

232

233 4. Innovations

234 Both the changing requirements for operational meteorologists and the diversity of student

10

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 235 backgrounds (geographically, but also diversity in prior knowledge) and interests have in-

236 spired us to introduce several course innovations. These innovations concern education

237 tools/infrastructure (sections 4i and ii), didactics and content (sections 4iii and further), and

238 are presented here along with motivation and examples.

239

240 i. Feedback

241 Prompt and accurate feedback is crucial for successful teaching (Chickering and Gamson

242 1987). In the earlier course setup, all student assignments were corrected and graded manu-

243 ally, which was labor intensive, and students would not receive feedback until days/weeks

244 later. Now, students submit their answers to the assignments via the online teaching platform

245 Brightspace and promptly receive the correct answers electronically. This allows students to

246 immediately check their work and talk with the lecturers about any questions that arise. More-

247 over, the reduced workload for the lecturers means that there is more time to help students

248 with specific issues. This approach makes the student responsible for their study progress ra-

249 ther than the lecturers. Students’ ability to engage in learning and their ability to reflect on

250 their own progress can lead to increased self-efficacy and self-confidence as students learn

251 that they can reach expected goals. This approach also allows students to reflect on their

252 learning strategies and gain study ownership. College readiness is enhanced when students

253 demonstrate this behavior. Teaching methods that lack sufficient attention to student motiva-

254 tion, engagement, goals, self-efficacy, and persistence are less likely to result in student learn-

255 ing gains (Conley and French 2014).

256

257 ii. Programming environment

258 To encourage an active learning environment, students handle meteorological model out-

259 put and observations in Python Jupyter Notebooks. Unifying the programming language to

11

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 260 Python prevents different data types from being investigated with different software tools. Py-

261 thon is a fast growing, open-source programming language and is frequently used amongst

262 meteorologists and climatologists. As such, programming skills in Python are beneficial for

263 future studies and working environments. Python notebooks allow for treating, plotting and

264 interpreting datasets together in an internet-based browser environment. As these notebooks

265 can also contain textual instructions and exercises, the notebooks combine the exercise in-

266 structions and programming tasks into one single document. Finally, the collection of Note-

267 books enables students to download and process open-source data by themselves in later

268 stages of their program.

269 Each notebook is set up in a similar way. First, the class specific learning outcomes are in-

270 dicated, together with the student activity (Figure 2). Thereafter, required libraries and the da-

271 taset(s) are loaded, and the spatiotemporal dimensions of the dataset can be explored. Subse-

272 quently, the notebook provides learning information and a clear question that needs to be an-

273 swered by editing the Python code. By executing the code block, the resulting figure appears

274 which in this case is a satellite image of the near infrared in MSG channel 4. Most Python

275 skills learnt in the modules should be applied in the ‘forecast product development’ module

276 (section 4v), where students build code to develop and visualize a forecast product.

277

278 iii. Intake

279 The university’s strategic education plan promotes personalized learning paths, where stu-

280 dents themselves choose which courses or modules they wish to take based on their prior

281 knowledge, interests and skills. Insight into the diversity of prior knowledge, skills and inter-

282 ests is collected through an online intake questionnaire four weeks prior to the start of the

283 course. For example, the questionnaire provides information about the students' geographical

284 backgrounds and knowledge of local weather systems, which facilitates the international

12

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 285 classroom (see section 4iv). In addition, the questionnaire collects information about attended

286 meteorology courses (BSc or MSc program, home university or foreign university) and com-

287 puting skills (see Supplementary material). The questionnaire helps to discover a student’s in-

288 terest in the different meteorological scales and the sub-disciplines within meteorology. With

289 the answers to the questionnaire, lecturers learn about the strengths and weaknesses of the stu-

290 dent cohort, enabling them to timely adapt the course content. For example, the lecturers have

291 prepared a collection of modules at either preparatory or deeper levels which allows them to

292 be somewhat flexible in offering certain modules depending on the course edition.

293 Concretely, one year the intake revealed that a substantial number of students were al-

294 ready working for weather companies in their spare time, e.g., as assistant meteorologists for

295 written or online media, or as a nighttime forecaster for road slipperiness. This prior back-

296 ground knowledge helps to shape the course content for these more advanced students, and

297 their work experience can be shared with the other students via short presentations.

298 The questionnaire contains a short self-assessment about student knowledge concerning

299 weather phenomena and analysis tools, e.g. about thermodynamic diagrams, synoptic obser-

300 vations and identification of fronts (Figure 3). Despite being taught in preceding courses, the

301 modest self-assessment scores underline the need for repeating these topics in the current

302 course.

303 iv. Internationalization

304 Nowadays, many meteorological work environments require a global understanding of

305 weather systems with customers and stakeholders all over the world, not to mention the multi-

306 plicity of nationalities and cultures amongst colleagues in the international labor market. As

307 such, the course should contain international aspects, which is achieved by a so-called interna-

308 tional classroom. Internationalization is the incorporation of international, intercultural and/or

13

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 309 global dimensions into the course content and the learning outcomes, assessment tasks, teach-

310 ing methods and support services (Leask 2015). Basically, international classroom comprises

311 three key components: i) English as the language of instruction, which is the case for our

312 whole BSc program, ii) Intercultural competence and iii) International framework. Intercul-

313 tural competence starts when reflecting on norms and values in different countries and the re-

314 alization that not all students will have had this reflection, and the appreciation that there are

315 many ways to be a good student. Students should develop new ways of learning that are help-

316 ful in their new learning context.

317 Students in well-functioning international classes, will be well prepared for an international

318 labor market and society. Students from different cultural backgrounds work together in an

319 international class and learn about new habits and ways of doing things that are different from

320 what they learned in their own countries. Students also learn to express themselves in a lan-

321 guage that is not their mother tongue (e.g. Apple et al. 2014). They also come across new

322 knowledge and other methods of teaching and assessment. These are all experiences that con-

323 tribute to successful functioning in an international environment. In part, these benefits also

324 apply to lecturers. They too have to deal with communicating in a different language with stu-

325 dents from other cultures. International students act as a mirror that shows how teaching

326 methods are shaped by beliefs and culturally determined norms.

327 We achieve an international classroom by inviting our foreign students to give presenta-

328 tions about the weather and climate of their home country and the forecasting challenges that

329 are posed. This is an example of so-called place-based teaching that is a fruitful manner that

330 supports inclusiveness (Apple et al. 2014). This covers both the physical and dynamic aspects

331 and the societal relevance of the phenomena. For instance, a Zimbabwean student presented

332 circulation in his country, how it had evolved during the recent decades in terms of

333 timing, intensity, and its impact on food production and the government’s food policy (Figure

14

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 334 4). Also, he reported about the relatively limited observational infrastructure in Zimbabwe,

335 and how seasonal forecasts are downscaled with the COSMO and WRF models. For native

336 students, such a short contribution is very meaningful since the curriculum lacks a course in

337 tropical meteorology.

338 Internationalization is also achieved through a graded weather briefing in which interconti-

339 nental actual weather phenomena are used (section 4vii). Based on the ECMWF extreme fore-

340 cast index, the lecturers select regions where interesting weather phenomena are forecast in

341 the coming 72 hours. Consequently, students are asked to make a weather forecast for this re-

342 gion, which implies that they need to invest time in understanding the driving physical and

343 dynamical mechanisms as well as the local vulnerability and stakeholders.

344 For example, students could be tasked with making a visibility forecast for dust storms in

345 northern Africa. These storms occur during relatively southerly positioned jet streams, com-

346 bined with high near surface wind speeds and relatively dry soils. Since dust is not a direct

347 model output, students have to explore the physical processes and empirical methods to trans-

348 late direct model output for that region to visibility. As a second example, so called Nor’east-

349 ers are macro-scale extratropical storms that impact the north Atlantic areas of the U.S.A.

350 Nor'easters are usually accompanied by heavy or , and can cause severe coastal

351 flooding, coastal erosion, hurricane-force , or blizzard conditions. Student forecasts

352 should address the case-specific societal impacts and assess their likelihood and occurrence,

353 for example, by examining soundings to quantify the possibility of snow.

354

355 v. Forecast product development

356 More and more forecaster jobs require skills to develop and implement forecast products for

357 specific applications and customers. This entails the capacity to digest and manipulate routine

15

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 358 NWP output (data science approach) and the presentation of a hands-on visualization and in-

359 terpretation for customers (Garbanzo-Salas and Jimenez-Robles, 2020). Hence, we introduced

360 an 8-hour assignment about processing direct model output (e.g. ECMWF or GFS) into a

361 powerful targeted forecast product (e.g. wind energy, clear air turbulence, road weather fore-

362 casts, rule-based forecasting). In practice, students are provided some peer-reviewed pa-

363 pers that present methods to forecast meteorological phenomena based on direct model out-

364 put. By reading these papers, students come to realize that scientific research has been the ba-

365 sis of the forecast method. Subsequently, students design a flowchart of the required input and

366 manipulation steps that need to be taken to calculate the indices. This flowchart also helps stu-

367 dents to build the structure of their Python code to calculate and plot their forecast in a Jupyter

368 notebook. As a by-product, students learn to think about a strategy for data management, pro-

369 gramming structure and data visualization, which are skills that are required in jobs in data

370 analytics and in academic research. Finally, students evaluate their own forecast against ob-

371 servations. With this assignment, students develop and evaluate their own forecast product,

372 and thereby, address the highest cognitive level of Bloom’s taxonomy (Anderson and Bloom

373 2001).

374 As an example, one product development assignment deals with clear air turbulence

375 (CAT). CAT forecasts are based on indices of contrasting complexity that account for hori-

376 zontal and vertical (|v/z|), convergence (Cvg), deformation (D), and atmospheric

377 stability, e.g., the Ellrod's turbulence index (T1) and the Ellrod and Knapp (1992) (T2) index.

378 T1 is defined as

휕푣 379 푇1 = 퐷 | |, 휕푧

380 Alternatively, T2 builds upon T1 and is defined as

휕푣 381 푇2 = (퐷 + 퐶 ) | |, 푣푔 휕푧

16

383 As an illustration of student work, Figure 5 shows the flowchart for the CAT forecast

384 based on T1 and T2. First, wind components are loaded from open-source GFS forecast files,

385 and subsequently the deformation, vertical wind shear and convergence are estimated, and fi-

386 nally combined in the metric of interest. Figure 6 shows the forecast which indicates the areas

387 with high risk of CAT at the 300 hPa level in yellow. Pilot reports of CAT taken in the hour

388 around the valid forecast time are plotted over the U.S.A. as forecast verification.

389

390 vi. Communication

391 Successful communication of weather forecasts to customer groups is as important as creating

392 a weather forecast from NWP model results (Eden 2011). Nowadays, the forecaster's focus

393 has evolved towards the role of storyteller, i.e., what does the weather forecast mean for a par-

394 ticular customer? This communication aspect was absent before the course revision and has

395 been introduced by means of an excursion to the weather room of DTN and a subsequent as-

396 signment. Here, a senior communication meteorologist presents the prerequisites for success-

397 ful forecast communication, illustrated with striking examples of how accurate and timely

398 communication prevented damage and casualties.

399 Initially, the chief meteorologist briefs the students about the weather expected in the

400 upcoming three days. The students are then asked to set up a communication strategy for dif-

401 ferent customers and different media based on the presented weather forecast. Importantly,

402 the focus is not on the meteorological aspects of the forecast itself, but on the strategy of how

403 to communicate the briefed forecast to the customers. The customer groups are the general au-

404 dience, aviation, road maintenance, agriculture, offshore, the energy sector, and organizers of

405 an outdoor festival. For each topic, two groups of two students get about one hour to prepare a

406 5-min presentation about their communication strategy. Subsequently, the strategies laid out

17

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 407 in the two presentations are commented on by fellow students and by the senior communica-

408 tion meteorologist. Thus, the students learn from each other in an active learning environ-

409 ment. This is where foreign students can bring in their experience on how communication is

410 different in their home country, facilitating the international classroom. Finally, during this

411 excursion, students learn how a dynamic and broadly oriented weather consultant agency op-

412 erates nowadays.

413 Figure 7 presents a sample communication strategy for flower farmers. First, crucial

414 weather variables for flower preservation are listed such as high wind speeds, hail and high

415 . Based on the briefed forecast, high chances of and hail storms with

416 some wind gusts were expected. Finally, the communication strategy included direct consulta-

417 tion with flower farmers and TV presentations for agriculture websites.

418

419 vii. Weather briefing by students

420 Some key activities of a forecaster include analyzing meteorological observations and model

421 data, selecting the most relevant information, synthesizing this information into a physically

422 consistent story, and communicating the forecast to customers and colleagues. This process

423 occurs under time pressure. Students follow these steps when creating and presenting a

424 weather briefing.

425 The weather briefing assignment focuses on analyzing the NWP output and its interpreta-

426 tion, while section vi focuses on proper forecast communication. A senior meteorologist from

427 DTN starts the assignment with a presentation about tips and tricks to structure a weather

428 briefing. Weather briefing assignments for selected place-based weather phenomena foreseen

429 in the coming 72 hours are distributed to student teams which are made up of two students.

430 Some phenomena might be new for them and require reading textbooks or online articles to

431 understand the physical and dynamic processes at hand. In the 4 hours of preparation, students

18

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 432 create a 12-min weather briefing aimed at a professional audience, which includes a Power-

433 Point file and an oral presentation.

434 After the briefing, presenting students interact with their peers, the lecturers and the senior

435 meteorologist from DTN. Students have to defend their forecasts in a short debate. The lectur-

436 ers underline the need to understand the physical processes behind the weather phenomenon

437 at hand and the awareness of the uncertainty of the presented forecast. In addition, they en-

438 courage students to use multiple data sources presented earlier in the course. After reflection

439 and interactions with more knowledgeable forecasters, students are able to connect processes

440 to underlying theory (Pandya et al. 2012).

441

442 viii. Model interpretation and model verification

443 Nowadays, critically assessing model results and their value is a crucial skill of a meteorol-

444 ogist in view of the large data volume available in the forecasting cycle. Hence, this skill must

445 be properly trained in our course to achieve the following educational goals for students

446 (Schultz et al. 2015):

447  learning how such models are constructed and run and working with model output;

448  recognizing that all models are wrong but some are still useful;

449  being able to identify those weather and air‐quality phenomena that can be well fore-

450 cast from those that cannot, whether it be due to resolution or unaccounted for physi-

451 cal or chemical processes;

452  understanding that a model simulation may have specific variables that it forecasts

453 well and variables that it forecasts less well.

454 The Atmospheric Practical covers model interpretation in several ways. In week 1, students

455 learn about temporal and spatial resolutions of both weather and climate/re-analysis models,

456 and how this affects different meteorological variables. Furthermore, after the student weather

19

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 457 forecast in week 2, students can directly verify their forecasts against one presented by a pro-

458 fessional meteorologist from DTN. As such, students can determine themselves in a rather

459 safe environment whether they structured the presentation similarly, and whether all crucial

460 weather elements were included in their own product. This collaborative instruction and expe-

461 riential education strengthen the operational–academic relationships and students’ apprecia-

462 tion of the intricacies of forecasting (Cohen et al. 2018). Also, in a module on Model Verifica-

463 tion students learn about different model verification techniques, such as bias, association, ac-

464 curacy, skill, reliability and discrimination. They also learn about skill scores for infrequently

465 occurring weather events using contingency tables and metrics such as hit rate, false alarm

466 rate, Heidke skill scores, ROC diagrams, etc. Students estimate these scores using archived

467 long-term forecast data and observations.

468 In addition, we familiarize students with “jumpiness” or “inconsistency” of model fore-

469 casts (Zsoter et al. 2009) through the so-called ‘flipflop index’ (Griffith et al. 2019), and stu-

470 dents practice with this index based on a recent set of forecasts for the same valid date. Model

471 jumpiness occurs when consecutive runs of a model provide substantially different solutions,

472 e.g., alternating cold or warm solutions in a situation when frontal zones are nearby but with

473 an uncertain timing. Students should learn that with substantial jumpiness, the latest model

474 run is not necessarily the best one to use for the actual forecast. Finally, during the forecast

475 product development module (see section 4v), students have to develop and verify a forecast

476 against observations. As such, students are forced to critically assess their own forecast, i.e.,

477 why they are successful or not.

478

479 5. Discussion

480 This section discusses educational innovations with respect to the requirements of operational

481 meteorologists and brings the presented course into perspective with regards to educational

20

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 482 efforts at other universities and meteorological institutes.

483 Scheduling reasons limit us to three weeks of full-time practicals. Given the short amount

484 of time available and given that some students have limited prior knowledge and practical ex-

485 perience, students are not fully prepared to run operations alone in a weather room after com-

486 pletion of the course. Nevertheless, the course provides students with a thorough introduction

487 to operational meteorology and training in basic skills to facilitate development towards be-

488 coming a skilled meteorologist. The course makes students aware of the multi-faceted world

489 of modern operational weather services and will assist students in making a choice for their

490 future (meteorological) career. Further training is provided in the MSc program, or by the hir-

491 ing public or private weather agency. WU offers courses in Atmospheric Dynamics, Numeri-

492 cal Techniques, and Atmospheric Modelling (Steeneveld and Vilà 2019).

493 WMO has formulated requirements in their BIP-M for certification of meteorologists

494 (WMO 2012, 2019) in the form of learning outcomes. Students enrolled in the Atmospheric

495 Practical gain a firm introduction to many aspects of these requirements. The learning out-

496 comes and the related modules from the course are presented in Table 1. In general, the

497 course treats many topics listed in the BIP-M at the correct cognitive level, but time con-

498 straints prevent us from including more practical training that would allow students to fulfil

499 the BIP-M requirements after completion of the course. For example, the Dutch National

500 Weather Service offers a 4-month training program that allows students to truly comply with

501 the BIP-M requirements.

502 Ideally, a deeper discussion of the forecast with stakeholders and customers in situations

503 that are critical for society would ideally be part of the course but cannot be trained in depth

504 due to the time constraints. For example, students in a simulation environment may be faced

505 with different roles and responsibilities during events occurring at an open-air

506 music festival. Apart from the role as the operational forecaster, roles such as mayor, festival

21

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 507 director, or head of the police department may help to allow the student to experience the pro-

508 cess of decision making in crisis situations. Alternatively, Eumetrain offers a set of meaning-

509 ful simulation environments in which a student is put into a training situation. For example,

510 students can be tasked to prepare a forecast for a planned flight where the crew may have to

511 handle fog (http://www.eumetrain.org/simulators/FogSimulator/sim.html) or deep convection

512 (http://www.eumetrain.org/simulators/ConvectionInTheCarpathianBasin/index.html).

513 Other universities also offer practical training in synoptic meteorology. Grundstein et al.

514 (2011) describes a severe weather laboratory exercise for an Introductory Weather and Cli-

515 mate class for freshmen that uses inquiry-based learning techniques. In the lab, students play

516 the role of meteorologists making forecasts for severe weather by utilizing collaborative

517 learning in teams. The study shows that important content knowledge is retained better in

518 comparison to a traditional lab approach and that students found the new lab more engaging.

519 While our course intends to serve students at the BSc level, we have chosen relatively high

520 cognitive educational learning objectives and since students should fulfil the learning objec-

521 tives individually, we support the laboratory approach.

522 Bond and Mass (2009) show that many students’ methods evolve over time in their course.

523 They report that only after the first few weeks do most students develop a consistent, com-

524 plete, and efficient procedure for examining a large amount of observational and NWP model

525 data and then effectively distil this information into a reasonable prediction. This indicates

526 that a 3-week course is a rather short amount of time to treat the basics of the forecasting cy-

527 cle.

528 Further course development is still needed to match expectations, wishes and time con-

529 straints. For example, we aim to revise the online intake interviews. Our first experience with

530 the intake questionnaire is that it helps students to open their minds to the course, learn about

22

Unauthenticated | Downloaded 09/28/21 11:35 PM UTC Accepted for publication in Bulletin of the American Meteorological Society. DOI 10.1175/BAMS-D-20-0107.1. 531 the expectations of the lecturers and their relative freedom. At the same time, the question-

532 naire raises expectations that we so far cannot always fulfil. In addition, the questionnaire

533 confirmed that student interests in themes, weather phenomena and sub-disciplines are broad,

534 which is challenging to accommodate. An advanced intake questionnaire should sense more

535 effectively a student’s intrinsic motivation to enroll in the course, and their viewpoint on their

536 future career as an operational meteorologist, all of which can be useful for further course de-

537 velopment.

538 The personal learning paths that the course introduces offer students the opportunity to fo-

539 cus on certain meteorological phenomena, especially in the forecast product development

540 module. Personal learning paths can be strengthened throughout the course. Ideally, we would

541 like well-prepared students to skip certain modules if they can prove sufficient prior

542 knowledge. Hence, these students can concentrate on more advanced topics than those that are

543 commonly available . In practice, however, it is challenging to organize and supervise stu-

544 dents with different tracks running in parallel. Moreover, requirements for the examination

545 and the student assessment may be diluted and become less transparent, which should be

546 avoided.

547

548 6. Conclusion

549 Recent innovations in the Atmospheric Practical course at Wageningen University (The Neth-

550 erlands), which prepares students to become a weather forecaster, are presented. Innovations

551 introduced in the course are: 1) the online student intake questionnaire; 2) the strong focus on

552 the role of a forecaster as a communicator, i.e. what is in the forecast for me as a stakeholder?;

553 3) the international classroom approach in which students from abroad bring in their

554 knowledge about weather phenomena in their home country; 4) the development of a forecast

555 product for specific weather phenomena for dedicated target groups (e.g. clear air turbulence

557 that forecast products have a scientific background and at the same time teaching students to

558 be critical towards these methods and assess their uncertainty; 5) the introduction of a unified

559 modern software tool (Python, with data analysis and visualization in Jupyter notebooks) that

560 enables students to download and analyze weather observations or model fields during as well

561 as after the course. The course facilitates an active approach where all aspects are trained and

562 assessed as a practical activity.
