Tornadoes have been more common in cooler periods of US climate history. Tornadoes are NOT a phenomenon associated with warming temperatures.
This is a map and list of tornadoes since 1950 which the National Weather Service has rated F5 (before 2007) or EF5 (equivalent, 2007 onward, the most intense damage category on the Fujita and Enhanced Fujita damage scales. The tornadoes are numbered in the order they happened since 1950; so the numbers run from the bottom up. NOTE: Since the (E)F-scale is a subjective damage assessment tool, official NWS ratings (as logged in Storm Data and in the NSSFC/SPC database) may differ on occasion from those of other tornado databases, such as those of the Tornado Project or University of Chicago.
There were more category 5 tornadoes in the 30 years before 1983 than in the 30 years after 1983.
