NASA Flies into the Face of Hurricane Research

For the first time in almost a decade NASA will study tropical cyclones in a massive field campaign.

The Genesis and Rapid Intensification Processes mission, or GRIP, will combine data acquired from three NASA aircraft and three NASA satellites to study the creation and rapid intensification of hurricanes starting on August 15 in a six-week campaign.

“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.”

Three NASA aircraft will be taking part in the mission, carrying a total of 15 instruments all designed to determine how a tropical cyclone will behave. A DC -8, WB-57 and a remotely piloted Global Hawk will all be available to monitor hurricanes in the Atlantic and Gulf of Mexico.

The instruments on board the aircraft will monitor many factors including cloud droplet and aerosol concentrations, air temperature, wind speed and direction in storms and on the ocean’s surface, air pressure, humidity, lightning, aerosols and water vapour.

The Tropical Rainfall Measuring Mission, TRMM, will provide rainfall estimates and help pinpoint the locations of “hot towers” or powerhouse thunderstorms in tropical cyclones. The CloudSat spacecraft will provide cloud profiles of storms, which include altitude, temperatures and rainfall intensity. And several instruments onboard NASA’s Aqua satellite, will provide infrared, visible and microwave data that reveal such factors as temperature, air pressure, precipitation, cloud ice content, convection and sea surface temperatures.

“It was a lot of hard work to assemble the science team and the payload for the three aircraft for GRIP,” Kakar said. “But now that the start of the field experiment is almost here, we can hardly contain our excitement.”

    Hello! My name is Goran and i live in Belgrade, Serbia. At the moment i am watching film "The 11th Hour" with Leonardo DiCaprio as narrator and i must say i am troubled with the way we are handling situation of global worming. We as humans are the problem for our own habitat and voice of ordinary people cannot be heard cause of powerful officials (governments and people of money and influence).
    I am not a religious fanatic or nearly religious as i should be, but it looks like we are all going forward to discover "the great design", but in the fact we are going in the wrong way. We are not settled with less but we want more and more. No one has stopped for a moment and enjoy in life and ordinary things such as air, water and simply breathing. As i am growing older (atm i have 30yrs), i am wishing for a place to live with full of forests, rivers, mountains, wildlife and a little cottage to have place to sleep.
    People should be afraid from mother nature, and fear is the only thing that will keep this planet safe from destruction and exploitations of human race.
    P.S. I am not part of any government, movement or any group. I am a consumer and i am ashamed what we did to our planet. I wish that humans will have enough intelligence and character to change our way of living and in that way to save the planet, our only place to stay free.
