| Abstract: | Rationalized by the observational circulation pattern in the upper ocean of the North Pacific, meridional friction term is
first incorporated in a barotropic theoretical model of the wind-driven circulation. The governing potential vorticity equation
thence has β term and wind stress curl term (the two of the Sverdrup balance), zonal friction term and meridional friction
term. The analytical solution satisfactorily captures many important features of the wind-driven circulation in the North
Pacific: Kuroshio, Oyashio, Kuroshio extension, North Equatorial Current, and especially the eastern boundary currents in
the North Pacific, i.e. California current and Alaska current. |
