Directional Wave Spectra Using Normal Spreading Function

Abstract

Purpose: To present a parameterized model of a directional spectrum of the sea surface using an energy spectrum and a value for the mean wave direction. l'he model used in this Technical Note is the Normal Spreading Function. Background: With the growing interest in directional spectral estimation and modeling of so-called "Spreading Functions," there is a need for methods by which the directional spectral density can be easily computed using various types of data. If one has data from directional then possible to estimate a directional spectrum raw data are not available but have been reduced spectrum and a mean direction estimate. This is addressed in this note.
