Envisat Sees Whirling Hurricane Katrina From Ocean Waves To Cloud Tops

Summary:
ESA's multi-sensor Envisat satellite has gathered a unique view of Hurricane Katrina in the Gulf of Mexico. While an optical image shows characteristic spiralling cloud patterns, a simultaneous radar observation pierces through the clouds to show how Katrina's 250-kilometre-an-hour an hour winds scour the sea surface.

Two separate views of Hurricane Katrina acquired 28 August 2005 from instruments aboard Envisat. The ASAR Wide Swath mode radar image of the sea surface shows how Katrina's wind fields are rippling the ocean. Beside it is the MERIS Reduced Resolution mode optical images showing characteristic swirling cloud patterns around the central eye, with the eye walls visible.
