On the wind driven circulation of the south Pacific Ocean.

Abstract

Applies a simple model of wind driven baroclinic circulation to the south Pacific Ocean. The wind driven Sverdrup transport is distributed among a number of layers so that potential vorticity is conserved. Outlines the model used and discusses the modelled circulation in the three layers. Compares computed baroclinic circulation with observations, noting good agreement in the deeper layers. Examines flow around New Zealand (transport stream function, western boundary current) and the east Australian current. Suggests the cross isopycnal mixing should be included in modelling of shallow circulation in tropiscal regions. (C.J.U.)
