    Study of a Numerically Modeled Severe Storm

Company / Institution / Agency:

  • National Center for Supercomputing Applications (NCSA)


    The understanding of severe storms begins by identifying pre-storm conditions. Using this initial environment, a thunderstorm’s complexity is modeled with a set of mathematical equations. These equations are solved on a supercomputer, then visualization techniques are employed to simulate the air flow and other features that exist during a storm’s lifetime.
