BACKGROUND Thunderstorms and prior grass pollen counts were investigated as predictors of daily hospital admissions for asthma in England. This study was motivated by reports in the literature of spectacular asthma epidemics associated with thunderstorms, particularly in the grass pollen season. METHODS Asthma admissions for two age groups (0-14 years and 15 and over) were measured using the ...

We are developing dynamic relational knowledge discovery methods for use on mesoscale weather data. Severe weather phenomena such as tornados, thunderstorms, hail, and floods, annually cause significant loss of life, property destruction, and disruption of the transportation systems. The annual economic impact of these mesoscale storms is estimated to be greater than $13B (Pielke and Carbone, 2...

Theoretical calculations suggest that sounds produced by thunderstorms and detected by a system similar to the International Monitoring System (IMS) for the detection of nuclear explosions at distances ≥100 km, are at sound pressure levels equal to or greater than 6 × 10(-3) Pa. Such sound pressure levels are well within the range of elephant hearing. Frequencies carrying these sounds might all...

A complex for measuring the electrical parameters of surface layer atmosphere, which has been successfully operating in Kamchatka since 1997, is described. The basic principles organization such measurements and methods their implementation under specific conditions are given. main reactions electric field to meteorological phenomena, as well seismic space events, shown. feature observatory tha...
