FY96 NCAR ASR Highlights
FY96 NCAR ASR Highlights 1996 ASR Highlights Highlights of NCAR's FY96 Achievements These are the most significant highlights from each NCAR division and program. Atmospheric Chemistry Division Highlights data missing Atmospheric Technology Division Highlights AVAPS/GPS Dropsonde System The development of the advanced Airborne Vertical Atmospheric Profiling System (AVAPS)/GPS Dropsonde System was close to completion at the end of FY 96. This work has been supported by NOAA and the Deutsche Forschungsanstalt fuer Luft- und Raumfahrt (DLR, Germany). AVAPS has now progressed to the point where all the NOAA data systems (two four-channel systems plus spares for the NOAA G-IV aircraft and two four-channel systems plus spares for the NOAA P-3 aircraft) have been delivered, and the initial flight testing has been completed. Both high-level (45,000-foot-altitude) and low-level (22,000-foot-altitude) drop tests have been completed, including intercomparison tests in which sondes were dropped from both the G-IV and the P-3s. Data taken by the AVAPS system on the G-IV and by a second system installed in a leased Lear 36 aircraft are expected to play a key role in the Fronts and Atlantic Storm Tracks Experiment (FASTEX), scheduled for early 1997. The DLR four-channel AVAPS system is currently being built and will be installed on the DLR Falcon aircraft in March 1997. NCAR has transferred the technology to the public sector by licensing a commercial firm (Vaisala, Inc.) to build future GPS sondes and data systems. This effort is led by Hal Cole and Terry Hock. -
High-Resolution Initialization and Simulations of Typhoon Morakot (2009)
MAY 2011 N G U Y E N A N D C H E N 1463 High-Resolution Initialization and Simulations of Typhoon Morakot (2009) HIEP VAN NGUYEN AND YI-LENG CHEN Department of Meteorology, University of Hawaii at Manoa, Honolulu, Hawaii (Manuscript received 19 May 2010, in final form 4 January 2011) ABSTRACT A model self-bogus vortex is constructed by cycle runs using the Weather Research and Forecasting (WRF) model to provide high-resolution initial conditions for tropical cyclone (TC) simulations. The vortex after 1 h of model simulation is used to construct the vortex structure for the initial conditions for the next cycle run. After about 80 cycle runs, the TC structure is well adapted to the model employed and well adjusted to the given large-scale conditions. Three separate simulations using three different initial conditions including global analysis (CTRL), the bogus package from WRF (WB), and the new initialization package (NT) are performed for Typhoon Morakot (2009). The NT scheme shows advantages in generating realistic vortex features including sea level pressure, winds, a warm core, and correct TC size with the meteorological fields away from the observed TC center consistent with the global analysis. The NT scheme also shows significant improvements in TC sim- ulations including asymmetric structure, track, intensity, strength of low-level winds, radar reflectivity, and rainfall. For other runs, such as WB and CTRL, the unbalanced initial vortex needs to adjust to the changing environment during the first 2–3 days of model simulations, which is likely to have negative impacts on the track, intensity, and rainfall forecasts in most cases. -

Dynamics of Track Deflection Associated with the Passage of Tropical Cyclones Over a Mesoscale Mountain
VOLUME 134 MONTHLY WEATHER REVIEW DECEMBER 2006 Dynamics of Track Deflection Associated with the Passage of Tropical Cyclones over a Mesoscale Mountain YUH-LANG LIN AND NICHOLAS C. WITCRAFT Department of Marine, Earth, and Atmospheric Sciences, North Carolina State University, Raleigh, North Carolina YING-HWA KUO Mesoscale and Microscale Meteorology Division, National Center for Atmospheric Research, Boulder, Colorado (Manuscript received 9 August 2005, in final form 21 February 2006) ABSTRACT In this study, the fifth-generation Pennsylvania State University–National Center for Atmospheric Re- search (PSU–NCAR) Mesoscale Model (MM5) was used to simulate Supertyphoon Bilis (in 2000) and Typhoon Toraji (in 2001) in order to investigate the dynamics of track deflection caused by the Central Mountain Range (CMR) of Taiwan. The MM5 predicted the track of each storm reasonably well. Bilis was stronger and had a relatively faster forward motion, which helped make the track continuous as it crossed the CMR. The use of a “bogus” vortex in the initialization process helped produce a storm closer to the observed strength. Bilis is a classic example of a typhoon crossing Taiwan with a continuous track. For comparison, Typhoon Toraji, a typical typhoon having a discontinuous track, was also studied. Toraji was weaker and had a relatively slower forward speed, which prevented the original low center from crossing over the CMR and forced more air parcels to go around the northern tip of the CMR. As a result, it produced a vortex and a secondary low center on the lee. Potential vorticity banners on the north side of the CMR acted to organize the secondary low and the lee vortex. -
An Overview of the China Meteorological Administration Tropical Cyclone Database
FEBRUARY 2014 Y I N G E T A L . 287 An Overview of the China Meteorological Administration Tropical Cyclone Database MING YING,WEI ZHANG,HUI YU,XIAOQIN LU, AND JINGXIAN FENG Shanghai Typhoon Institute, China Meteorological Administration, Shanghai, China YONGXIANG FAN National Meteorological Center, China Meteorological Administration, Beijing, China YONGTI ZHU AND DEQUAN CHEN Shanghai Typhoon Institute, China Meteorological Administration, Shanghai, China (Manuscript received 18 May 2012, in final form 4 July 2013) ABSTRACT The China Meteorological Administration (CMA)’s tropical cyclone (TC) database includes not only the best-track dataset but also TC-induced wind and precipitation data. This article summarizes the charac- teristics and key technical details of the CMA TC database. In addition to the best-track data, other phenomena that occurred with the TCs are also recorded in the dataset, such as the subcenters, extratropical transitions, outer-range severe winds associated with TCs over the South China Sea, and coastal severe winds associated with TCs landfalling in China. These data provide additional information for researchers. The TC-induced wind and precipitation data, which map the distribution of severe wind and rainfall, are also helpful for investigating the impacts of TCs. The study also considers the changing reliability of the various data sources used since the database was created and the potential causes of temporal and spatial inhomogeneities within the datasets. Because of the greater number of observations available for analysis, the CMA TC database is likely to be more accurate and complete over the offshore and land areas of China than over the open ocean. -
Typhoons Affecting Hong Kong: Case Studies
Typhoons affecting Hong Kong: Case Studies by S. Campbell The Hong Kong University of Science and Technology A report submitted for the APEC 21st Century COE Short Term Fellowship April 2005 Abstract This report, “Typhoons affecting Hong Kong: Case Studies”, accompanies the main document concerning wind-induced damage in Hong Kong, entitled “History of Wind Damage in Hong Kong”. The case studies presented in this report offer the raw data collected from a selected number of storms that have severely damaged Hong Kong or highlighted its vulnerability to typhoons. For a summary of the overall effects of wind and wind-induced damage in Hong Kong, the reader is advised to examine “History of Wind Damage in Hong Kong”. The reader wanting more detail into specific damage occurring during typhoons is recommended to also read this report. This report contains data and qualitative reports from the Hong Kong Observatory, newspapers (published in English) and other sources. While information from the Hong Kong Observatory and newspapers can generally be trusted, other sources, although being valuable, may be anecdotal. Nevertheless, the gathered information is presented as raw data with few comments from the author, thus providing an unbiased account as to what happened during each typhoon. In addition to “The History of Wind Damage in Hong Kong” and this report, the following is also provided in electronic format for future use solely by the staff and students at Tokyo Polytechnic University: a) A tabulated summary of quantitative typhoon measures and damage categories in the file “COE_WindDamage_HK.xls”. This table contains all relevant typhoon-induced damage data collected between the years 1957 to 2004, inclusive. -
Coincidence of Storm Surges and River Discharges Due to Typhoons in the Pampanga Delta
Coincidence of storm surges and river discharges due to typhoons in the Pampanga delta Master Thesis H.J. aan het Rot Cover image: Satellite image of Typhoon Nesat in 2011 above the Pampanga delta (NASA, 2011). 2 Coincidence of storm surges and river discharges due to typhoons in the Pampanga delta Master Thesis Herm Jan aan het Rot University of Twente Faculty of Engineering Technology Department of Water Engineering and Management P.O. Box 217 7500 AE Enschede The Netherlands Author: Herm Jan aan het Rot [email protected] Supervisors: Prof. dr. J.C.J. Kwadijk University of Twente Dr. ir. M.J. Booij University of Twente Dr. ir. J.V.L. Beckers Deltares Delft, Oktober 2018 3 SUMMARY Highlights - Taking into account the joint occurrence of storm surges, discharge peaks and high tides is of major importance in exposure and risk studies in the Pampanga delta; - Simulated inundations in the largest part of the Pampanga delta are dominated by river discharges but can be strengthened by storm surges; - In some areas in the surroundings of Manila Bay and in north-western Manila the simulated inundations are dominated by the combination of storm surges and tides; - There is a significant increase of the joint probability of extreme storm surges and extreme discharges in comparison with the independent probability. The Pampanga delta (Philippines) is due to its geographical location prone to typhoons which can result in extreme discharges and storm surges in Manila Bay. In most flood risk studies, river discharges and storm surges are considered independent, but if there exists dependence between storm surges and river discharges, this might have a significant influence on design levels and expected inundations. -

WORLD METEOROLOGICAL ORGANIZATION WMO TROPICAL METEOROLOGY RESEARCH PROGRAMME (TMRP) COMMISSION FOR ATMOSPHERIC SCIENCES (CAS) TOPIC CHAIRMAN AND RAPPORTEUR REPORTS OF THE FOURTH WMO INTERNATIONAL WORKSHOP ON TROPICAL CYCLONES (IWTC-IV) HAIKOU, CHINA 21-30 APRIL 1998 WMO/TD - No. 875 Secretariat of the World Meteorological Organization Geneva, Switzerland 1998 NOTE The designations employed and the presentation of the material in this publication do not imply the expression of any opinion whatsoever on the part of the Secretariat of the World Meteorological Organization concerning the legal status of any country, territory, city or area, or of its authorities, or concerning the delimitation of its frontiers or boundaries. This report has been produced without editorial supervision by the WMO Secretariat. lt is not an official WMO publication and its distribution in this form does not imply endorsement by the Organization of the ideas expressed. Foreword This is the fourth in a series of very successful workshops organized through the World Meteorological Organization's Tropical Meteorology Programme. The concept of bringing together researchers and operational forecasters from all parts of the globe for discussion and interaction has proved to be enormously successful. The previous three meetings have produced significant tangible outcomes in the form of publications and forecaster guidance, and have recommended directions for organizations to pursue with respect to tropical cyclones. There are also a number of intangibles surrounding these workshops that may be equally significant in the longer term. The broadening of links between individuals and organizations, the cross-fertilisation of ideas and the raising of awareness about exciting advances that are taking place around the world are all contributing towards the amelioration of the impact of tropical cyclones. -
A Chronology of Notable Weather Events by Douglas V. Hoyt
A Chronology of Notable Weather Events by Douglas V. Hoyt Edition of 8/4/2011 243 A. D. An inundation of the sea in Lincolnshire laid under water many thousands of acres (Camden). 353 Flood in Cheshire in which 3000 people died along with thousands of cattle (Hayden). 402 Euxine Sea frozen over for 20 days (Hayden) 500 The Vandals from Poland held Western Africa, the Diocese of Africa, Visigoth (Western Goth) from Scandia held Spain, Ostrogoth (Eastern Goth) from Scandia held Italy, Germanic-Franks from Scandia held Gaul, Burgundians held Rhone river, and Celts, Germanic-Anglo-Saxon held the diocese of England. The massive migration of the Mongols, the Huns, Goth, Slav-Bulgars, and Avars westward is because of adverse weather conditions driving them from their lands . The Germanic-Danes inhabited the Danish Islands, Schonen, and later Jutland. St. Brendan (521-527) in his voyage to the northwest suggests the Celts of Ireland discovered America about this time. The Polynesian reached Hawaii and established agricultural settlements. These people had traveled 2500 miles from Island to Island. It is inconceivable that these peoples didn't reach America in the past 500 years. The Polynesians colonized Hawaii, Easter Island, and Madagascar by 500 A.D. 507 Men from Tsinngan, China report being blown across the Great Sea East to a people who speak a strange language. 508 In England, the rivers were frozen for more than two months (including Thames?). Possible severe winter. Rivers frozen for two months. Years also quoted as 507 or 509. 514 St. Brendan (484-577) of Ireland explored the area discovering the Hebrides, Orkney, Faeroe Islands and Iceland, starting about this time. -
