Steady Topographical Perturbation of a Zonal Current in the Northern Hemisphere

Abstract

The periodic solution of the governing differential equation of steady topographical perturbation of a zonal current, which is obtained in the previous papers without taking into account of latitudinal variation of Coriolis' parameter, is applied to compute the streamlines of zonal current over the Northern Hemisphere zone by zone from 75 deg N to 15 deg N in comparison with the actual Normal Contour Chart. Distributions of horizontal velocity divergence and vertical component of vorticity accompanied by these computed streamlines are discussed together with La Seur's deviation of circulation center.
