Presets
A tornado's winds follow the Rankine vortex model: inside the core the air spins like a solid disk, with speed rising straight out to a peak at the core edge; outside, the wind falls off as 1/r. The fastest, most destructive winds ring the core, not the very center — which is why the eye of a vortex is deceptively calm.

About this simulation
The full Tornado Vortex tool models an El Niño year with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
