absolute_vorticity

absolute_vorticity(rvo)

Computes the absolute vorticity from a relative vorticity Fieldset.

Parameters

rvo (Fieldset) – relative vorticity (1/s)

Return type

Fieldset

The computation of absolute vorticity is based on the following formula:

\[2\Omega sin\phi + rvo\]

where:

  • \(\phi\) is the latitude

  • \(\Omega\) is the Earth’s angular velocity (1/s).

The ecCodes paramId of the resulting fields is set to 3041 (absolute vorticity).
