Question:
What is the rotational energy of an average U.S. tornado?
Replies:
Writing on USA Toady's weather page,
(http://www.usatoday.com/weather/wtwistqa.htm),
Joe Schaefer, director of NOAA/NWS Storm Prediction Center in Norman
Oklahoma states that the typical tornado contains 10,000 kilowatt/hours
of energy.
That is about the energy used by an old fashioned incandescent 60 watt
light bulb burning continuously for 19 years. The reason a tornado does
so much damage is that all that energy is packed into a very small space.
A hurricane has one million times the energy but that's spread over hundreds
or thousands of square miles.
