Jets on a giant planet

Change planetary rotation and wind speed. Compare the Rhines scale with the width of the coloured latitude bands and follow advected tracers.

The model and its limits

Prescribed zonal flow guided by the Rhines scaling. Procedural clouds are tracers, not a solution of compressible atmospheric dynamics.

Equations used in the module

Equations
β = 2Ω/R; L_R = √(U/β); cloud tracers follow a prescribed zonal flow

Impact and the ejecta curtain

Choose the target body and the impactor. The atmosphere brakes, breaks or bursts it; the crater takes its scaled size and shape; the ejecta fly with the speeds of their launch positions, the fastest escaping small bodies.
