Automated extraction and classification of thunderstorm and non-thunderstorm wind data for extreme-value analysis

Design wind loads are partly based on extreme value analyses of historical wind data, and limitations on the quantity and spatial resolution of wind data pose a significant challenge in such analyses. A promising source of recent wind speed and direction data is the automated surface observing system (ASOS), a network of about 1000 standardized US weather stations. To facilitate the use of ASOS...

Thunderstorm distribution and frequency in Australia

Thunderstorms are spectacular but hazardous weather phenomena which, together with tropical cyclones and bushfires, top the list of concerns in the Bureau of Meteorology’s Severe Weather Warning Services Program. Insurance-related claims arising from thunderstorms (wind, hail and flash flood damage) from 1967 to 1999 amount to about $A5 billion (Insurance Council of Australia 2000). The Sydney ...

Rising Variability in Thunderstorm-Related U.S. Losses as a Reflection of Changes in Large-Scale Thunderstorm Forcing*

Thunderstorm-related normalized economic and insured losses in the United States east of the Rockies from the period 1970–2009 (March–September) exhibit higher peaks and greater variability in the last two decades than in the preceding two decades. To remove the bias from increasingly detected losses over time due to newly built-up locations, only large events that incurred normalized losses of...
