weatherbench2.derived_variables.GeostrophicWindSpeed

class weatherbench2.derived_variables.GeostrophicWindSpeed(geopotential_name='geopotential')

Calculate geostrophic wind speed.

Geostrophic wind is only meaningful when the Coriolis force is significant (small Rossby number), i.e., away from the equator, where it is undefined.

This was suggested as a diagnostic for physical balance in AI weather models by Massimo Bonavita in https://arxiv.org/abs/2309.08473
