Steamwise Vorticity in a Supercell Thunderstorm Simulation
By Chris Rodriguez |
This animation, created from the dataset of a simulated hypothetical thunderstorm, compares vortex (gold) with wind velocity (grey to red by speed). The scene illustrates rotation in the updraft, the hallmark characteristic of a supercell.
