ATLANTIC, Va.—NASA scientists are using former military surveillance drones to help them understand more about how tropical storms intensify, which they say could ultimately save lives by improving forecast models that predict a hurricane's strength.
The unmanned Global Hawk aircraft were designed to perform high-altitude, long-endurance reconnaissance and intelligence missions for the Air Force. Two of the original Global Hawks built in the developmental process for the military have found new life as part of NASA's research mission, studying storms that form over the Atlantic Ocean. NASA planned to launch one of the drones from its Wallops Flight Facility on Wednesday to study Tropical Storm Gabrielle, which re-formed in the Atlantic on Tuesday.
"The biggest scientific question we're trying to attack is why do some hurricanes intensify very rapidly and why do others not intensify at all? In the last 20 years, we've made terrific progress in forecasting where hurricane tracks will go," said Paul Newman, deputy project scientist for the research mission. "But we've made almost no progress in the past 20 years in forecasting intensity."
