Rapid Scan Operations (RSO) images of the GOES-13 10.7 µm IR channel (above) showed some interesting evolution of Tropical Storm Hanna on 05 September 2008. Strong bursts of convection were seen to develop near the center of Hanna, with periods of cloud top temperatures colder than -80º C (purple colors).A... Read More

Hurricane Ike intensified into a  Category 4 storm late in the day on 03 September 2008. A comparison of GOES-12 10.7 µm IR and SSM/IS 85 GHz microwave images from the CIMSS Tropical Cyclones site (above) showed a... Read More

A series of low-level “outflow boundaries” was seen on GOES-13 visible imagery (above), propagating westward from the shield of high clouds associated with Tropical Storm Hanna, moving across the Bahamas on 03 September 2008. The air behind each of these pulses appeared to be quite dry, judging from the general... Read More

Tropical Storm Hanna exhibited some interesting satellite imagery features on 02 September 2008. GOES-13 IR images (above) displayed a period of transverse banding during the 01-05 UTC period — this transverse banding is a satellite signature of potential turbulence (although  no aircraft...
