Just after Tropical Cyclone 11S formed in the Southern Indian Ocean NASA’s Aqua satellite passed overhead gathering data using infrared light. The Atmospheric Infrared Sounder or AIRS instrument aboard NASA’s Aqua satellite looked at Tropical Cyclone 11S in infrared light. The AIRS image was taken on Mar. 8 at 20:41 UTC (3:41 p.m. EST) and showed some cloud top temperatures of thunderstorms around the center of circulation as cold as minus 63 degrees Fahrenheit (minus 53 degrees Celsius). NASA research has shown the storms with cloud tops that cold have the potential to generate heavy rainfall.
