wavespectra.SpecArray.partition#

SpecArray.partition(wsp_darr, wdir_darr, dep_darr, swells=3, agefac=1.7, wscut=0.3333)[source]#

Partition wave spectra using Hanson’s watershed algorithm.

This method is not lazy, make sure array will fit into memory.

Args:

  • wsp_darr (DataArray): wind speed (m/s).

  • wdir_darr (DataArray): Wind direction (degree).

  • dep_darr (DataArray): Water depth (m).

  • swells (int): Number of swell partitions to compute.

  • agefac (float): Age factor.

  • wscut (float): Wind speed cutoff.

Returns:

  • part_spec (SpecArray): partitioned spectra with one extra dimension representig partition number.

Note:

  • Input DataArrays must have same non-spectral dims as SpecArray.
