After
a busy start, tornado events in the U.S. in 2012 have dropped well
below the expected normal. The preliminary total of 757 tornadoes is
about 400 tornadoes below what might be expected in a typical year. This
chart shows that in late 2011, the annual running total was over 400
tornadoes above normal. This depicts the dramatic variability that can
occur in tornado numbers from one year to the next. |
