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. -

The History of Wind Damage in Hong Kong
The History of Wind Damage in Hong Kong 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, entitled “The History of Wind Damage in Hong Kong”, provides a summary of wind and wind-induced damage in Hong Kong. This report is accompanied by another document, called “Typhoons affecting Hong Kong: Case Studies”. For a concise summary of the overall effects of typhoons in Hong Kong, the reader is advised to examine this report. The reader wanting more detail into specific events during typhoons is also recommended to read “Typhoons affecting Hong Kong: Case Studies”. In this report, a review of the risk of people and buildings to typhoon hazards is discussed. Then, the wind climate of Hong Kong is presented and analyzed with respect to its potential hazards. Next, the design of buildings in Hong Kong is discussed with regards to buildings Codes. It is noteworthy that the “Code of Practice on Wind Effects in Hong Kong 2004” was just released, making 2005 a transition year between the new Code and the “Code of Practice on Wind Effects Hong Kong – 1983”. Finally, a summary of wind-induced damage and its effects on Hong Kong as a whole is presented. It was observed that the amount of wind-induced damage has generally decreased since the earliest records in Hong Kong. It is reasoned that the most important factor leading to this decrease is better communication. Additional factors responsible for reduced damage are also discussed. -
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. -
Tropical Cyclone Warnings of Signal No. 8 Or Above Issued by the Observatory During the Passage of Dot in October 1964
Tropical cyclone warnings of Signal No. 8 or above issued by the Observatory during the passage of Dot in October 1964 Local Storm Warning issued at 1:20 p.m. on 12 October 1964 by the Royal Observatory. Local Storm Warning Signal No.7* was hoisted at 1:10 p.m., which means that gale or storm force winds with mean speed 34 knots or more are expected from the northeast quarter. At 1 p.m., Typhoon Dot was centred near 20.2 degrees north, 115.0 degrees east, that is about 140 miles south-southeast of Hong Kong. It appeared to be moving in a more northerly direction which would bring it to within 70 miles of Hong Kong. Winds in the circulation are probably about 70 knots. Winds over the Colony are generally strong and increasing. During the last hour, gusts of 66 knots have been recorded at Tate’s Cairn and 44 knots at the Airport. Local Storm Warning issued at 2:30 p.m. on 12 October 1964 by the Royal Observatory. Local Storm Warning Signal No.7* is still hoisted, which means that gale or storm force winds with mean speed 34 knots or more are expected from the northeast quarter. At 2 p.m., Typhoon Dot was centred near 20.3 degrees north, 115.0 degrees east, that is about 135 miles south-southeast of Hong Kong. It appeared to be moving in a more northerly direction which would bring it to within 60 miles of Hong Kong tomorrow morning. Gale force winds have been reported about 50 miles south of Hong Kong. -

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.
