Three-hourly synoptic reports from over 15,000 weather stations and a large number of marine platforms for 1976-1997 were analyzed to create a global seasonal and annual climatology for each of the following extreme
weather phenomena: thunderstorms, hailstorms, and
squalls/funnel clouds/tornados. The regional and seasonal variations will be discussed. The mean diurnal cycle of these extreme events will also be analyzed.
