In recent years, the detection of the existence of mesoscale eddies in different parts of oceans has been considered as one of the greatest advances made in the field of physical oceanography. As a result, the classical theory of mean oceanic circulation is challenged and the science of physical oceanography has been advanced from the stage of the study of 'ocean climate' to that of 'ocean weather'. As a matter of fact, eddies contain much more energy than the mean oceanic circulation does, and, what
