In early August 2005, Katrina was just a name. By September, it had become synonymous with the costliest and one of the deadliest tropical cyclones in U.S. history.
Five years later, NASA is revisiting Hurricane Katrina with a short video that shows the storm as captured by NASA satellites. NASA provides space-based satellite observations, field research missions, and computer climate modeling to further scientists’ understanding of these storms. NASA also provides measurements and modeling of global sea surface temperatures, precipitation, winds and ocean heat content — all ingredients that contribute to the formation of tropical cyclones (the general name for typhoons, tropical storms and hurricanes).
