Tornadoes are as much a part of the landscape here in the south as are pine trees. But any meteorologist will tell you it's hard to pinpoint their exact path more than a few minutes before they hit.
Now NASA-supported researchers say that gravity waves, which are similar to waves in the ocean except they roll through the air, can hit a rotating thunderstorm and cause a tornado to form. The scientists at the National Space Science and Technology Center in Huntsville, Alabama, will soon be training meteorologists all over the country to look for these gravity waves in hopes of improving tornado forecasts.
