Vapor is the Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers. Vapor is developed at the National Center for Atmospheric Research, and runs on both Unix and Windows platform. While the visualization looks neat, it would be even better if it had a color bar, instead of blue equals cold fluid, red equals hot fluid in the notes of the video.

Two different views of the same simulation of Rayleigh-Benard-Convection.

Blue = cold fluid, red = hot fluid.
