How is it that with nearly 200 nations in the world, just one—the United States—gets up to three-quarters of all tornadoes? On top of that, we average about a dozen supertwisters yearly.

Supertwisters have winds exceeding 200 miles per hour. This puts them at the extreme end of the Fujita Scale of Tornado Intensity (the so-called F4 and F5 tornadoes).

Ideally, forecasters could warn people before these funnels hit. Unfortunately, this is not always the case.
But maybe forecasting will improve. Watch today’s video as scientists look for a supertwister.
