. Access Feature: Stormy Weather
  These images of a thunderstorm on June 16, 1997, were generated at NCSA with forecast data from the Center for Analysis and Prediction of Storms at the University of Oklahoma. In the top image, rain, ice, snow, and cloud were rendered as isosurfaces so that the boundary of each moisture variable was easy to distinguish. Rain is purple, ice is gray, snow is a translucent teal, and clouds are blue. In the smaller image, only rain was rendered as an isosurface. The other variables were combined and rendered volumetrically, which is more lifelike, using values that increased from black to white.
