Infrared data from NASA's Aqua satellite have watched the strong thunderstorms in Typhoon Bopha fizzle and shrink in area over the weekend as wind shear increased. Bopha has now dissipated in the South China Sea, just west of Luzon, Philippines.
NASA's Aqua satellite has been providing data on Bopha since the day it formed on Nov. 26. In the storm's last days, Aqua's Atmospheric Infrared Sounder (AIRS) instrument captured infrared data of the storm and showed that cloud top temperatures warmed from Dec. 8 through Dec. 9 as cloud heights fell and thunderstorms lost their punch.
AIRS infrared data reveals where the coldest, highest cloud tops are located in a tropical cyclone. The coldest cloud tops indicate the strongest storms with the heaviest rain. On Dec. 8, AIRS data revealed a large area of strong thunderstorms surrounded the center of circulation as the storm skirted the west coast of Luzon, the northern Philippines. That same day, Bopha triggered more warnings for the Philippines.
