Tornado climatology

The United States experiences by far the most tornadoes of any country, and has also suffered the most intense ones. Tornadoes are common in most states in spring and summer, especially those east of the Rocky Mountains. However, tornadoes can occur in the West as well, although they are usually very small and relatively weak. Recently tornadoes have struck the Pacific coast town of Lincoln City, Oregon, in 1996 and downtown Salt Lake City, Utah, in 1999 (see Salt Lake City Tornado). Canada also experiences numerous tornadoes, although less than the United States. Tornadoes do occur throughout the world as well; the most tornado-prone region of the world, as measured by number of reported tornadoes per unit area, is the United Kingdom, especially England http://www.torro.org.uk/severeweather/tornadofaqs.htm. New Zealand, Bangladesh and portions of Uruguay also have pockets of strong tornadic activity. Tornadoes have recently hit parts of Germany in 2003 and Pakistan in 2001 as well. The U.S. state which has the highest number of tornadoes per unit area is Florida, although most of the tornadoes in Florida are either F0, F1, or waterspouts.
