GEOSTROPHIC EDDIES IN THE OCEAN. PART I.

Abstract

The results of observations of eddies with dimensions of several kilometers to a few hundred kilometers are reviewed. Detailed measurements of an eddy off California revealed the quasi-geostrophic structure of the eddy of intermediate size. Eddies in the eastern half of the Gulf of Mexico are described from hydrographic data collected since 1950. Case histories and dynamical structure of eddies generated by cutoff of increasing meanders of the GulfStream and the Kuroshio are discussed. Generation of eddies and perturbations in the ocean due to moving meteorological disturbances are explained from examples in case of extra-tropical cyclones in the ocean polar front of the North Pacific and the one in case of hurricane in the central Gulf of Mexico. Dynamics on development of eddies due to a shearing instability are briefly reviewed. (Author)
