How is tornado intensity measured

But no one knows exactly what quantity or combination of those factors results in a twister. The only way to know for sure that a given weather condition will produce a tornado is if one actually appears. In fact, tornado forecasting was once so uncertain that meteorologists at the U. Weather Bureau were discouraged from issuing tornado forecasts until Ted Fujita, a Japanese-born American meteorologist who specialized in severe storms. Fujita felt that the Beaufort scale , an method of empirically estimating wind speed by examining the behavior of natural and man-made objects dust, loose paper, bodies in the breeze, was inadequate.

Theodore Fujita. All tornadoes, and other severe local windstorms, were assigned a number according to the most intense damage caused by the storm. The EF scale uses three-second wind gust estimates based on a more detailed system for assessing damage, taking into account different building materials.
