mpas_tools.mesh.creation.mesh_definition_tools.RRS_CellWidthVsLat(lat, cellWidthEq, cellWidthPole)[source]¶

Create Rossby Radius Scaling as a function of lat. This is intended as part of the workflow to make an MPAS global mesh.

Parameters:

lat (ndarray) – vector of length n, with entries between -90 and 90, degrees
cellWidthEq (float, optional) – Cell width in km at the equator
cellWidthPole (float, optional) – Cell width in km at the poles

Returns:

cellWidthOut (ndarray) – 1D array of same length as lat with entries that are cell width as a function of lat

Examples

>>> RRS18to6 = EC_CellWidthVsLat(lat, 18., 6.)
