Diagnostic calculation of two Kuroshio states

The major objective of the present paper is to make the diagnosis of two Kuroshio states and to analyze them from the point of view of their specific features and to make the comparison with the situations discussed in the literature. Another target of the paper is to extend the diagnostic approach created for the analysis of the baroclinic instability of the atmospheric motions (cf., Holton, 1979) to studying the ocean process. This approach has been used by Wang and Ikeda (1993) for the investigation of the ocean currents instability.
