Hurricane Igor Shows 170F Temperature Difference
Posted by 1969 on 9/15/2010, 6:28 am
This impressive infrared image of Hurricane Igor from NASA's AIRS instrument shows a clear and large eye, and very strong convection (purple)
and high, powerful thunderstorm cloud tops around his center.
The image was captured from the AIRS instrument on NASA's Aqua satellite on Sept. 14 at 14:47 UTC (10:47 a.m. EDT).
Note the warm ocean temperatures (dark orange) well over the 80 degree F threshold needed to maintain intensity.

When NASA's Aqua satellite passed over Igor on Sept. 14 at 14:47 UTC (10:47 a.m. EDT) the Atmospheric Infrared Sounder (AIRS) instrument
captured icy cold cloud top temperatures in the strong thunderstorms that surround Igor's well-defined eye.
Those cloud top temperatures were as cold or colder than -90F,
indicating they were near the top of the troposphere, and very strong.
