Balanced Versus Geostrophic Wind-Stress for Hudson Bay

Wind-stresses for Hudson Bay for May and September were computed by the geostrophic relation and the balance equation, making use of data averaged over 30 years. The balanced wind-stress for either strong (September) or weak (May) pressure gradient situations was found to be substantially different...

Description
Summary:Wind-stresses for Hudson Bay for May and September were computed by the geostrophic relation and the balance equation, making use of data averaged over 30 years. The balanced wind-stress for either strong (September) or weak (May) pressure gradient situations was found to be substantially different from the corresponding geostrophic stress. The wind-generated circulations in the water in Hudson Bay calculated using the balanced and the geostrophic wind-stress showed significant differences, the former agreeing better with the observed average circulation.
