Three NASA aircraft will begin flights to study tropical cyclones on Aug. 15 during the agency's first major U.S.-based hurricane field campaign since 2001. The Genesis and Rapid Intensification Processes mission, or GRIP, will study the creation and rapid intensification of hurricanes. One of the major challenges in tropical cyclone forecasting is knowing when a tropical cyclone is going to form. Scientists will use the data from this six-week field mission to better understand how tropical storms form and develop into major hurricanes.
Mission scientists will also be looking at how storms strengthen, weaken and die. "This is really going to be a game-changing hurricane experiment," said Ramesh Kakar, GRIP program scientist at NASA Headquarters in Washington. "For the first time, scientists will be able to study these storms and the conditions that produce them for up to 20 hours straight. GRIP will provide a sustained, continuous look at hurricane behavior at critical times during their formation and evolution."
GRIP is being led by Kakar and three project scientists: Scott Braun and Gerry Heymsfield of NASA's Goddard Space Flight Center in Greenbelt, Md., and Edward Zipser of the University of Utah in Salt Lake City. Three NASA satellites will play a key role in supplying data about tropical cyclones during the field mission. The Tropical Rainfall Measuring Mission, or TRMM, managed by both NASA and the Japan Aerospace Exploration Agency, will provide rainfall estimates and help pinpoint the locations of "hot towers" or powerhouse thunderstorms in tropical cyclones.
