wavespectra.core.npstats.tps

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

Smooth peak wave period Tp.

Parameters:

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

• spectrum (-) – Direction-integrated wave spectrum array E(f).

• freq (-) – Wave frequency array.

Returns:

Period of the maximum energy density in the smooth spectrum.

Return type:

• tp (float)

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.
