A hurricane is a heat engine spun up by a deep low-pressure center. The deeper the pressure drop, the fiercer the winds — see the relationship live.

pressure drives the wind

Presets
A hurricane is a giant heat engine whose winds are driven by the pressure drop at its center — the deeper the low, the fiercer the winds, roughly as the square root of the pressure deficit. The calm eye sits in the middle, ringed by the eyewall of strongest wind. Central pressure is the single best predictor of a storm's intensity.

How it works
The winds of a tropical cyclone are driven by the pressure deficit at its center, rising roughly as the square root of that deficit. A calm eye sits at the core, ringed by the eyewall of peak wind. Central pressure is the single best gauge of intensity, mapping to the Saffir-Simpson categories. Educational model, not an operational forecast.

Is this hurricane wind pressure model tool really free?▾
Yes. Hurricane Wind Model runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?▾
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?▾
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?▾
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
