TRMM Observes Storm Moving From California Eastward

Images are routinely produced using TRMM Microwave Imager (TMI) data which show the global area covered by the satellite. These "Quick Look" images use Microwave brightness temperatures at 85.5 GHZ and at 37.0 GHZ combined in the red, green and blue components (guns) of the images. These false color images can be used to distinguish land from water and show the differences between land surfaces such as deserts, snow cover and sea ice. On these images areas of dry atmosphere over water appear as blue and moist atmosphere is dark blue.

Storm Structure and Mesoscale Dynamics

Seeing Through the Clouds

Satellites allow us to observe changes in the precipitation structure over the life cycle of a storm, even over ocean and regions where conventional data are sparse. In particular, we now have insights into the dynamics of a storm, such as how the eye of a hurricane stays stable as the storm moves across the Earth’s surface, and how tropical cyclones intensify through the presence of “hot tower” structures.
