WAVE SLOPES, ACCELERATION AND VELOCITY OF THE OCEAN SURFACE -- MEAN SQUARE SPACE AVERAGES.

Abstract

The main objective of this investigation was to interpret and present the results of field measurements made by the National Institute of Oceanography, using a cloverleaf buoy and to compare these results with a development of a semi-empirical method for estimating the expected space average slope, vertical acceleration and velocity of the ocean surface for any given wind condition. Results of the chi-square test indicate that the distribution of slopes is in general Gaussian, while the acceleration distribution frequency shows non-Gaussian behavior. It was concluded that (1) the assumption of the wave system being composed of non-interacting linear deep water gravity waves with random phasing seems reasonable, that (2) the cosine square law for the angular dependence did not seem to be substantiated, and that (3) Phillips' spectrum may be used to estimate the space average values of the total slope and acceleration for higher wind conditions.
