Non-spectral methods of analysis of the internal gravity waves measurements in ocean

Abstract

The paper is devoted to the presentation of the non-spectral methods of analysis of the natural measurements of the internal gravity waves in the ocean with the purpose to determine characteristics of the wave-trains composing the measured field, the forms and parameters of the ocean along the pass of these wave-trains propagation. The problem of the analysis of the data of the natural measurements of the internal waves with the purpose to separate the single wave-trains from the measured field, and on this basis to determine the characteristics of these wave-trains, to receive the information on the sources of excitation of the waves, and the information on the properties of the ocean along the pass of the waves propagation, is directly connected with the problems of the wave dynamics. The basis of the offered algorithms of the analysis is the supposition, that the measured wave field represents the sum of the plane wave-trains having the certain speed and directions of propagation. Transformation of the packages of the internal waves, which can be determined by the given methods, may testify about the passage of the wave-trains through the big-size oceanic formations, that makes it possible to remotely determine the characteristics of these formations.
