wavespectra.partition.partition.np_ptm3

wavespectra.partition.partition.np_ptm3(spectrum, spectrum_smooth, freq, dir, parts=3, ihmax=100)

PTM3 spectra partitioning on numpy arrays.

Args:

• spectrum (2darray): Wave spectrum array with shape (nf, nd).

• spectrum_smooth (2darray): Smoothed wave spectrum array with shape (nf, nd).

• freq (1darray): Wave frequency array with shape (nf).

• dir (1darray): Wave direction array with shape (nd).

• parts (int): Number of partitions to compute, all detected by default.

• ihmax (int): Number of discrete spectral levels in WW3 Watershed code.

Returns:

• specpart (3darray): Wave spectrum partitions sorted in decreasing order of Hs with shape (np, nf, nd).

Note:

• The smooth spectrum spectrum_smooth is used to define the watershed boundaries which are applied to the original spectrum.
