Recently, scientists used data from NASA's Tropical Rainfall Measuring Mission satellite to analyze transformations that take place inside a hurricane. <br /><br />Recently, scientists used data from NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite to analyze transformations that take place inside a hurricane. Stephen Guimond, a graduate research assistant at Florida State University, Tallahassee, Fla., lead a study that used TRMM data to view the height at which ice melts near the core of several tropical cyclones (the generic name for hurricanes or tropical storms), including Hurricane Ophelia in 2005.<br /><br />“The temperature structure of a tropical cyclone is directly related to a storm’s wind speed and rainfall, which indirectly affects the storm surge,” Guimond said. It is important to monitor a storm’s thermal structure because this information assists meteorologists in estimating the impact on threatened areas of high winds, flash flooding and large storm surge.<br /><br />Many tropical cyclones transform into what are called “extra-tropical storms” as they move northward out of the tropics and into the mid-latitudes. During this stage, the storm’s cloud structure and high winds spread out over a wide area. As a result, the potential for heavy rainfall and large storm surge increases far from the center, potentially affecting life and property of more areas in the hurricane's path.<br /><br />When Guimond and his colleagues at the Naval Research Laboratory in Monterey, Calif. looked at the data from TRMM’s Precipitation Radar instrument, they could
