oceanspy.compute.Okubo_Weiss_parameter(od)[source]

Compute Okubo-Weiss parameter. Vertical component of relative vorticity and shear component of strain are interpolated to C grid points.

\[OW = S_n^2 + S_s^2 - \zeta^2\]
Parameters
od: OceanDataset

oceandataset used to compute.

Returns
ds: xarray.Dataset
Okubo_Weiss: Okubo-Weiss parameter
