Orange represents ocean temperatures at 82 degrees Fahrenheit or higher. This is the temperature required for hurricanes to form. The bottom left window shows wind analysis model data from NASA's Modeling, Analysis, and Prediction (MAP '05) program. The top right window shows rainfall accumulation for Hurricane Katrina from the TRMM spacecraft. The bottom right window shows energy-releasing deep convective clouds (as high as 16 km) in the eyewall of Hurricane Katrina. These clouds, called hot towers, formed on August 28 while the storm was intensifying to a category 5 hurricane.
