NASA Tropical Weather

September 11, 2013 - 5:35 AM
At 7:29 a.m. EDT on Sept. 3, 2013 NASA's Global Hawk 871 departed from the runway at NASA's Wallops Flight Facility in Wallops Island, Va. This was the first takeoff of GH 871 from Wallops for this aircraft, since it was not here last year. The aircraft is flying to the Caribbean to study a low pressure area that could become a tropical cyclone in a few days. NASA is using former military surveillance drones to help study how tropical storms intensify. The unmanned Global Hawk aircraft are taking off from NASA’s Wallops Flight Facility on the Eastern Shore of Virginia, where they’re studying storms that form over the Atlantic Ocean. NASA officials say while forecasting models predicting a storm’s path have improved greatly over the past few decades, there hasn’t been much progress producing models that predict a hurricane’s strength.
