Climatology Soundings for the Southeast US (3-hourly times)

Soundings were created by compositing all available soundings in each area (click here for map).  Hours displayed here were required to have at least 100 days worth of radiosonde observations.  To eliminate the potential bias that extra soundings were taken on severe weather days, the climatology sounding could not have a higher percentage of days with tornado reports than occurred for the entire time period for that region (e.g., FL had tornado reports on 6.6% of cool season days from 1950-2001, so hours having less than 6.6% of their soundings taken on tornado days are displayed here).
