A Simple Tornado climatology

We were interested in learning a bit about the tornado climatology as reported in the SELS Final Storm Log. To establish the climatology, we chose to search for tornado reports that were Over 1600 SAO stations/identifiers were considered. Instead of counting total tornadoes, only tornado days are considered. This eliminates problems with multiple counts of the same tornado. If a city has more than one SAO site that made the top ten list, only one entry is made for that city and the identifier associated with the highest count is listed.

For the period of 1950-1994 and for different ranges of F-ratings, the top ten locations and number of tornado days in the SELS Final Storm Log are:

SAO site
25-km radius
Tornado days
1950-94
F0-F5
