A severe thunderstorm climatology for Australia and associated thunderstorm environments

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-related asthma: what happens and why.

The fifth report issued by the Intergovernmental Panel on Climate Change forecasts that greenhouse gases will increase the global temperature as well as the frequency of extreme weather phenomena. An increasing body of evidence shows the occurrence of severe asthma epidemics during thunderstorms in the pollen season, in various geographical zones. The main hypotheses explaining association betw...

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 ...
