Video: Hurricane Katrina at Peak Intensity

In this video sequence by the Advanced Visualization Lab at NCSA, the dramatic formation of Hurricane Katrina is explored using advanced simulation techniques.

Scientists at the Advanced Visualization Laboratory at the National Center for Supercomputing Applications crunched terabytes of data gathered by the National Center for Atmospheric Research in Boulder, Colorado, to help create an amazing simulation. It creates an appropriate sense of foreboding for the impending disaster. Bulbous clouds gather moisture and deadly winds gain power as they travel across the warm water of the Gulf of Mexico, about to wreak havoc on New Orleans.
