NASA AIRS Infrared Image of System 94B (image) NASA/Goddard Space Flight Center Caption The AIRS instrument on NASA's Aqua satellite captured this image of System 94B's cold cloud tops on Dec. 6 at 3:11 p.m. EST. Most of the strongest convection and highest, coldest cloud tops remained off-shore over the waters of the western Bay of Bengal. Those cloud top temperatures were as cold as or colder than -63 degrees Fahrenheit (-52 Celsius) and appear in purple.
