Weather Data Visualization

The animation shown on the picture above was done with weather simulation data. The time sequence data were generated from a supercomputer. A commercial scientific visualization system was used to generated three dimensional objects.

Each time step data have objects including: cloud and rain water fields; wind streaks (streamlines); temperature isosurfaces. Like any conventional animation all these three dimensional objects were rendered and then reduced to two dimensional images. The time sequence images were then process into a movie showing in here.

It was very expensive to produce this kind of animation. About 10 years ago, the animation data generation had to be done with a supercomputer that cost about millions of dollars. Now a workstation or a high-end PC can do the similar job. A commercial scientific visualization system is still relatively expensive. It costs somewhere from few thousand dollars to more than ten thousand dollars. However, today we can do with a public domain software system.
