Results from numerical calculations of wind-driven ocean circulation with a barotropic model with bottom friction and on the β-plane are presented for a range of … WebGeostrophic currents. For most of the ocean volume away from the boundary layers, which have a characteristic thickness of 100 metres (about 330 feet), frictional forces are of minor importance, and the equation of motion for horizontal forces can be expressed as a simple balance of horizontal pressure gradient and Coriolis force.This is called geostrophic …
