The Weather in Germany in December 2016 an Extremely Sunny and Exceptionally Dry December The weather in Germany in December 2016 An extremely sunny and exceptionally dry December Offenbach, 29 December 2016 –– December 2016 was the third sunniest since measurements began in Germany and it was exceptionally dry. At the same time, the month was also relatively warm. Areas of high pressure brought plenty of sunshine, but also fog that persisted. Lowland areas were often covered by a thick layer of cold air, causing frost to prevail, at least at night. At Christmas, the influence of high pressure was interrupted by Atlantic troughs, bringing mild air, rain and, in the north, stormy weather. Thus, the only areas where any snow could be found during the festive season were at places above 1,000 metres. This is what the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. In December often warmer in the mountains than in the lowlands The average temperature for Germany in December was 2.1 degrees Celsius (°C), which is 1.3 degrees warmer than the average for the international reference period 1961–1990. Compared to the 1981–2010 period, the deviation was +0.9 degrees. At the beginning of the month, the continuous period of high pressure over Germany caused a layer of cold air to form near the ground. During this time, the mercury in low-lying areas failed to rise above freezing all day, whereas the temperatures prevailing in the mountains were comfortably above freezing. The leeward effects in areas close to mountains allowed the high temperatures to dominate even down to lowland areas. This was demonstrated on 8 December in Wernigerode on the northern edge of the Harz Mountains, where a temperature of 15.5 °C was recorded. Just the previous day, at a temperature of -12.1 °C, the DWD had recorded the coldest night of the month at Fichtelberg-Hüttstadl in the Fichtel Mountains. Christmas was mild but significantly cooler than in 2016. Much too dry, very little snow and no white Christmas With around 25 litres per square metre (l/m²), which is just 35 per cent of the long-term average of 70 l/m², December was much too dry. This made it one of the twelve driest December months since measurements first began in 1881. Low pressure areas or extensions of these managed to interrupt the continuous influence of high pressure only occasionally. This then brought rain. However, this year, too, the snow that many people were waiting for was absent almost everywhere. A blanket of snow made an appearance for a few days only in the Ore Mountains and on the edge of the Alps, as was the case in Garmisch-Partenkirchen on 19 December, when 12 cm was recorded. The most precipitation fell in the Ore Mountains, with some places seeing a total of more than 130 l/m², whereas with just 1 l/m² in places, the least precipitation was recorded on the south-east edge of the Black Forest. The highest daily precipitation figure of 26.7 l/m² was on 27 December in Zinnwald-Georgenfeld in the Ore Mountains. Third sunniest December in 2016, only surpassed by 1972 and 2015 With around 65 hours, December sunshine was 170 per cent of its long-term average of 38 hours. This made December 2016 the third sunniest December in Germany since such measurements first began in 1951. The most sunshine was recorded in the south, with some areas receiving almost 150 hours. Sunshine in some places was therefore nearly 500 per cent of the average. Some areas of Schleswig-Holstein, however, barely saw 25 hours of sunshine during the whole month. 1/1 .

  • 1/2 the Weather in Germany in Spring 2020 Exceptionally
    The weather in Germany in spring 2020 Exceptionally sunny, fairly warm and far too dry Offenbach, 29 May 2020 – As in the previous year, the spring of 2020 was fairly warm. For most of the time, the weather in Germany was dominated by warm air, with just a few short cold snaps. At first, spring 2020 continued the trend of warmer-than-average months, which had started in June 2019 and only ended this May, when the temperature anomaly became slightly negative. Frequent high pressure produced one of the sunniest spring seasons since records began; at the same time, precipitation remained significantly below average. This has been announced by the Deutscher Wetterdienst (DWD) after an initial analysis of the observations from its approximately 2000 measuring stations. Mild March and warmer-than-average April followed by slightly too cool May The average temperature in the spring of 2020 was 9.2 degrees Celsius (°C), 1.5 °C above the average of the international standard reference period 1961–1990. Compared to the warmer 1981–2010 reference period, the deviation was 0.7 °C above normal. Spring began with a mild March, which, however, saw a drop in temperature around the 20th with maximum temperatures often not exceeding single-digit figures. April, too, was significantly too warm, even belonging to the seven warmest April months since measurements began in 1881. May was slightly too cool, despite some stations in the south registering up to seven summer days with temperatures over 25 °C. This spring’s nationwide maximum temperature of 29.4 °C was recorded in Lingen in the Emsland on 21 May.

  • Offenbach, 30 January 2015 – Frequent Weather Systems Coming in from the West Brought Varied Weather to Germany in January 2015
    The weather in Germany in January 2015 Year of record temperatures in 2014 followed by a much too warm January 2015 Offenbach, 30 January 2015 – Frequent weather systems coming in from the west brought varied weather to Germany in January 2015. Everything was included, from spring-like warmth with record temperatures and severe storms to brief wintry interludes. Overall, the month was very mild with high precipitation and little sunshine. This is what the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. Periods of spring-like warmth with record temperatures Following on from the year of 2014, which was the warmest since records began, January 2015, too, saw a positive temperature anomaly. At 2.1 degrees Celsius (°C), the average temperature was 2.6 degrees higher than the international reference value for 1961 to 1990 of -0.5°C. Compared to the warmer period 1981 to 2010, the deviation was +1.7°C. The influence of high pressure prevailed at the start of the month, but brought weather with little cloud cover only to the south. This caused the temperature over the snow cover existing there to fall and give hard frosts. Leutkirch-Herlazhofen in the Württemberg part of the Allgäu recorded the lowest temperature in January with -15.2°C in the night to 1 January. After that, lively westerly winds, which generally brought very mild air masses, prevailed under the influence of low pressure during the first twenty days of the month. On 10 January, the storm depression ‘Felix’ brought spring-like warmth to Germany.

  • Indicators of Hemeroby for the Monitoring of Landscapes in Germany
    Indicators to monitor the structural diversity of landscapes Ulrich Walz Leibniz Institute of Ecological Urban and Regional Development, Weberplatz 1, 01217 Dresden, Germany Ecological Modelling 295 (2015) 88–106, http://dx.doi.org/10.1016/j.ecolmodel.2014.07.011 ABSTRACT An important level of biodiversity, alongside the diversity of genes and species, is the diversity of ecosystems and landscapes. In this contribution an indicator system is proposed to measure natural diversity (relief, soils, waters), cultural diversity (main land use classes, diversity of land use, ecotones, connectivity) and anthropogenic impacts (fragmentation, hemeroby, protection).The contribution gives an overview of various indicators on landscape diversity and heterogeneity currently used in Germany andEurope. Based on these indicators a complementary system, is presented. The indicators introduced here are derived from regular evaluations of the digital basis landscape model (BasicDLM) of the Authoritative Topographic-Cartographic Information System (ATKIS), the digital land cover model for Germany (LBM-DE) as well as other supplementary data such as the mapping of potential natural vegetation. With the proposed indicators it is possible to estimate cumulative land-use change and its impact on the environmental status and biodiversity, so that existing indicator systems are supplemented with meaningful additional information. Investigations have shown that indicators on forest fragmentation, hemeroby or ecotones can be derived from official geodata. As such geodata is regularly updated, trends in indicator values can be quickly identified. Large regional differences in the distribution of the proposed indicators have been confirmed, thereby revealing deficits and identifying those regions with a high potential for biodiversity. The indicators will be successively integrated into the web-based land-use monitor (http://www.ioer-monitor.de), which is freely available for public use.

  • A Guide to Bryologically Interesting Regions in Germany
    A GUIDE TO BRYOLOGICALLY INTERESTING REGIONS IN GERMANY with contributions by K. von der Dunk, R. Lotto, R. Lübenau and G. Philippi edited and translated by Jan-Peter Frahm prepared for a bryological fieldtrip during the XIV Botanical Congress, Berlin 1987 THE FICHTEL MOUNTAINS by Klaus von der Dunk 1. General Information 1.1 Location The Fichtelgebirge is situated in the northeastern part of Bavaria and is enclosed to the north and East by the borders of the German Democratic Republic and the CSSR. The name "Fichtel"gebirge probably does not link with the spruce trees (Fichte = Picea abies), which is much abandoned today, but there is a word conjunction with some kind of sprites, called "Wichtel" in German, who are supposed to live in dark woods. The Fichtelgebirge has the shape of a horseshoe open to the east The interior part with the city of Wunsiedel is in about 600 m altitude. The surrounding mountains raise up to 1000m (Schnee-berg, Ochsenkopf). The Fichtelgebirge is part of the main water draining line: three rivers flow to the North Sea (Saale, Eger, Main), while the fourths (Naab) flows (via Danube) to the Black Sea. 1.2. Geology The Fichtelgebirge lies beyond a famous fault, the so-called Fränkische Linie (Fig.1). This fault divides the mesozoic layers of sedimentary rocks in the Southwest from the granitic igneous rocks in the Northeast. The mountain area itself consists of granite, now and then intruded by magma, especially in the southern part. In several places one can see large basalte quarries. The higher elevations of the granitic massif are often eroded to solitary rocks called "Blockmeere".

    Physico-chemical surface water conditions of catchments with metallogenic origin: A contribution to the establishment of the EC Water Framework Directive 2000/60/EG in Germany Peter L. Neitzel1, Petra Schneider1, Helmut Schlumprecht2 1Hydroisotop-Piewak GmbH, Oberfrohnaer Str. 84, D-09117 Chemnitz 2Büro für Ökologische Studien, Alexanderstr. 5, D-95444 Bayreuth Abstract: For the realisation of the EC Framework Water Directive in Germany, the reference conditions of metals in surface waters have to be determined taking into consideration the so called surface water landscape. In catchments of metal- logenic origin metals and radionuclides like uranium influence the quality of the surface waters. In this study, the quality status of metallogenic (Ore Mountains, Harz, Rhine Slate Mountains) and other surface water landscapes were compared in order to differentiate factors influencing the natural background in similar geo- logical formations. Introduction In the year 2000 the EC Water Framework Directive (2000/60/EG) passed the par- liament of the European Community (EC), which then became legal law in all countries of the EC. The main objective of the EC-directive is to achieve a good quality of all surface, ground-, estuary and coastal waters. This includes an as- sessment of the chemical status of the surface waters (environmental quality stan- dards for nearly 30 priority compounds and substances) and a five-stage ecologi- cal classification of waters. According to the regulations three groups of characteristics are important for the European surface waters, namely: hydrobiol- ogy (priority), hydromorphology (supporting hydrobiology) and physico-chemical conditions (supporting hydrobiology). “High water quality” (class I) hence reflects natural conditions totally, while class II refers to “good water quality”.

  • 1/1 the Weather in Germany in November 2019
    The weather in Germany in November 2019 A mild month that was somewhat too dry with below-normal sunshine Offenbach, 29 November 2019 – Low-pressure areas mostly determined the weather in November 2019. During the first ten days of the month, these areas of low pressure followed a direct course from the west to central Europe, frequently bringing precipitation and mild air. They then skirted Germany so it still remained dry in spite of the low air pressure. During this time, the temperatures were often dependent on the dispersal of the fog and low stratus cloud cover, which then occurred frequently. In summary, November was somewhat too mild and too dry yet with below-normal sunshine. This is what the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. A predominantly mild November At 5.2 degrees Celsius (°C), the average temperature in November was 1.2 degrees higher than the figure for the international reference period for 1961–1990. Compared to the warmer reference period 1981–2010, the temperature was 0.8 degrees higher. Inflows of subtropical air temporarily reached large swathes of Germany at the start of November. These caused the mercury to rise to over 17 °C on 2 November, with Ohlsbach near Offenburg registering the highest November temperature of 20.1 °C. The rest of November was much cooler, but it was still mild. In the second and third ten-day periods, temperatures were frequently determined by the dispersal of fog and low stratus cloud cover as well as the position of low-pressure areas.

Discussion started: 2 November 2017 c Author(s) 2017. CC BY 4.0 License. Potential future exposure of European land transport infrastructure to rainfall-induced landslides throughout the 21st century Matthias Schlögl1,2 and Christoph Matulla3 1Transportation Infrastructure Technologies, Austrian Institute of Technology (AIT), Vienna, Austria 2Institute of Applied Statistics and Computing, University of Natural Resources and Life Sciences (BOKU), Vienna, Austria 3Department for Climate Research, Zentralanstalt für Meteorologie und Geodynamik (ZAMG), Vienna, Austria Correspondence to: Matthias Schlögl ([email protected]), Christoph Matulla ([email protected]) Abstract. In the face of climate change, the assessment of land transport infrastructure exposure towards adverse climate events is of major importance for Europe’s economic prosperity and social wellbeing. Robust and reliable information on the extent of climate change and its projected future impacts on roads and railways are of prime importance for proactive planning and the implementation of targeted adaptation strategies. Among various menacing natural hazards, landslides stand out as 5 most destructive hazards to the functional effectivity and structural integrity of land-bound transport systems, since they cause long-lasting downtimes and exceedingly expensive repair works. Periods of heavy precipitation persisting over several days are known to be a major trigger for increased landslide activity. Along with climate change such events can be expected to increase in frequency, duration and intensity over the decades to come. In this study, a Climate Index (CI) picturing rainfall patterns which trigger landslides in Central Europe is analyzed until 10 the end of this century and compared to present day conditions.

Late Cretaceous to Paleogene exhumation in Central Europe – localized inversion vs. large-scale domal uplift Hilmar von Eynatten1, Jonas Kley2, István Dunkl1, Veit-Enno Hoffmann1, Annemarie Simon1 1University of Göttingen, Geoscience Center, Department of Sedimentology and Environmental Geology, 5 Goldschmidtstrasse 3, 37077 Göttingen, Germany 2University of Göttingen, Geoscience Center, Department of Structural Geology and Geodynamics, Goldschmidtstrasse 3, 37077 Göttingen, Germany Correspondence to: Hilmar von Eynatten ([email protected]) Abstract. Large parts of Central Europe have experienced exhumation in Late Cretaceous to Paleogene time. Previous 10 studies mainly focused on thrusted basement uplifts to unravel magnitude, processes and timing of exhumation. This study provides, for the first time, a comprehensive thermochronological dataset from mostly Permo-Triassic strata exposed adjacent to and between the basement uplifts in central Germany, comprising an area of at least some 250-300 km across. Results of apatite fission track and (U-Th)/He analyses on >100 new samples reveal that (i) km-scale exhumation affected the entire region, (ii) thrusting of basement blocks like the Harz Mountains and the Thuringian Forest focused in the Late 15 Cretaceous (about 90-70 Ma) while superimposed domal uplift of central Germany is slightly younger (about 75-55 Ma), and (iii) large parts of the domal uplift experienced removal of 3 to 4 km of Mesozoic strata. Using spatial extent, magnitude and timing as constraints suggests that thrusting and crustal thickening alone can account for no more than half of the domal uplift.
