NASA launching mission to study hurricanes


A new NASA mission aims to come to grips with the way nature whips up hurricanes.

Set to begin Sunday, the agency's six-week Genesis and Rapid Intensification Processes (GRIP) mission will see a series of planes outfitted with sophisticated instruments take to the skies in an attempt to understand the birth of a hurricane, in order to give people a better chance to prepare for them.

This is NASA's first domestic hurricane project since 2001 and its largest ever. Three NASA planes, several satellites, and four planes from research partners will team up to measure tropical storms as they build in intensity or die out and weaken. The goal is to gather data into the process that transforms tropical storms into full-blown hurricanes to better forecast what they'll do when they hit land..

Currently, weather forecasters can predict the path of a storm fairly accurately. But they have trouble predicting its intensity, one of the biggest challenges in the field. Both factors are needed to help people determine how best to prepare before a hurricane reaches shore. If the hurricane is more intense then forecast, lives can be lost. If it's weaker than predicted, the public may start to ignore warnings to evacuate future storms.

Aircraft flying in the GRIP mission over the Gulf of Mexico and the Atlantic Ocean will include NASA's Global Hawk, an unmanned aircraft built by Northrop Grumman and typically used for surveillance; the WB-57, which conducts high-altitude research; and the DC-8, which also specializes in scientific research. The various planes will fly a precise and coordinated pattern at different altitudes and locations over the storms to monitor them as they develop..

"That's what makes this really unique, the ability to observe one of these storms up close as it changes over its life cycle..

"We want to see storms that become hurricanes, and we want to see some that don't become hurricanes, so we can compare the data."
