摘要

Abstract

Based on a simple conceptual model of stratified ocean

the criterion of the geostrophic velocity inversion in and below the thermocline was derived ash′·ν′<0 and {ie1-1}

meaning that the slopes of the thermocline (h′) and the sea {ie1-2} must be opposite to each other

and thath′ must be strong enough to satisfy the latter inequality. The criterion was applied to discuss the features of the western boundary undercurrents

the counter undercurrents of the western boundary currents below the thermocline

and to discuss the dynamics of their formation finally resulting from the combination of the basin-scale circulation and local geostrophic balance. The formation mechanism

multicore structure

and transport variations of the Mindanao Undercurrent and those of other undercurrents

such as the North Equatorial Undercurrent and the Kuroshio undercurrent

can be satisfactorily explained by the above results.
