Latitudinal derivative or Rossby Parameter

Computes latitudinal derivative of the coriolis parameter using [Wallace2006] (Eqn. 7.25 on pg. 288),

\[\beta = \frac{\partial f}{\partial y} = \frac{2 \Omega \cos \phi}{R_E}\]

where \(R_E\) is the radius of the earth

Parameters:

coriolis_param (DataArray) – Array of coriolis parameter values

Return type:

DataArray
