For the last five years, NOAA has teamed up with NASA to fly NASA’s Global Hawk unmanned aircraft to get an inside look at how hurricanes form and intensify over the Atlantic. The NASA-led project called the Hurricane and Severe Storm Sentinel mission is demonstrating the ability of the Global Hawk to fly over hurricanes to gather continuous weather data on flights that are longer in duration than possible with manned aircraft. In the next three years, NOAA will take the next step with the Global Hawk, leading a new experiment and continuing its important collaboration with NASA. Drawing on technology and expertise honed in the current mission, NOAA will assess the feasibility of regular operations of Global Hawk to improve day-to-day forecasts of severe storms forming over the Atlantic, Pacific and Arctic oceans.
