Hurricane Formation Simulator (2D)

Interactive 2D top-down hurricane-formation simulator: warm ocean water fuels rising vapor while the Coriolis force spins it into spiral rainbands, an eyewall, and a calm eye — tune sea-surface temperature and rotation strength and watch the storm organize in real time.

This top-down 2D simulator reimplements the same hurricane-formation mechanic as the 3D version using a flat canvas view: warm ocean water evaporates and rises while the Coriolis force curls that rising air into spiral rainbands, a dense eyewall, and a calm central eye once conditions cross the real tropical-cyclogenesis thresholds — sea-surface temperature above about 26.5°C and meaningful rotation away from the equator. Raise the sea-surface temperature and dial in mid-latitude Coriolis strength to watch a disorganized cluster of convection spin up into a full tropical cyclone, tracked live through central pressure, organization percentage, and eye clarity.

Interactive 2D top-down hurricane-formation simulator: warm ocean water fuels rising vapor while the Coriolis force spins it into spiral rainbands, an eyewall, and a calm eye as sea-surface temperature and rotation strength are tuned.
