earthkit.meteo.wind.xarray.coriolis

earthkit.meteo.wind.xarray.coriolis(lat)

Compute the Coriolis parameter.

Parameters:

lat (xarray.DataArray) – Latitude (degrees)

Returns:

The Coriolis parameter (\(s^{-1}\))

Return type:

xarray.DataArray

Notes

The Coriolis parameter is defined by the following formula:

\[f = 2 \Omega sin(\phi)\]

where \(\Omega\) is the rotation rate of Earth (see earthkit.meteo.constants.omega) and \(\phi\) is the latitude.
