pierson_moskowitz_spectrum(freq, fp, hs)

Calculate the Pierson-Moskowitz omni-directional wave spectrum for the specified frequencies and parameters.

This is included as one example of a spectrum function.

Return is in units of $m^2/Hz$.

Parameters:

• freq (float | ArrayLike) – Wave frequencies.

• fp (float) – Peak frequency of the sea-state in $Hz$.

• hs (float) – Significant wave height of the sea-state in $m$.

Return type:

float | ndarray
