wavespectra.core.npstats.tps(ipeak, spectrum, freq)

Smooth peak wave period Tp.

Args:

• ipeak (int): Index of the maximum energy density in frequency spectrum E(f).

• spectrum (1darray): Direction-integrated wave spectrum array E(f).

• freq (1darray): Wave frequency array.

Returns:

• tp (float): Period of the maximum energy density in the smooth spectrum.

Note:

• The smooth peak period is the peak of a parabolic fit around the spectral peak. It is the period commonly defined in SWAN and WW3 model output.
