tps_gufunc(x1, x2, x3, /, out=None, *, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj, axes, axis])

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.
