Summary

Tornado frequency over the past 33 years has increased, with an average of 858 tornadoes per year in the 1970s and 1200 per year in the 1990s. However, when plotted as "tornado days," the increase is less pronounced, with only small changes seen over the period 1970-2002. The number of strong and violent tornadoes has remained relatively constant, while the number of reported weak (F0) tornadoes has increased significantly, accounting for 64% of reported tornadoes between 1998-2002. Long-track and very-long-track tornadoes remain a small percentage of all reported tornadoes.
