Dear Tom,
Are there other countries that experience as many tornadoes as the United States
does?

Tom Skill, Peotone, Ill.
Dear Tom,
Nowhere in the world do more tornadoes occur than in the United States. The
latitude, geography and climate of this country provide a perfect breeding
ground for tornadoes unsurpassed anywhere in the world. As a result the U.S.
lays claim to nearly three-quarters of the world's twisters, the vast
majority occurring east of the Rockies.

However, tornadoes can and do occur in other parts of the world with the exception of
the polar regions. Areas with significant tornadic activity include Europe, Australia,
Canada, Russia, Argentina, China and Japan. In Bangladesh, at least a dozen twisters
have killed more people than the U.S.'s deadliest storm, the 1925 Tri-State tornado with
695 fatalities.
