On the decay of the meanders of eastward currents

The separation of western boundary currents from the coast and their eastward extensions into the open ocean are characterized by the presence of quasi-stationary, large-scale meanders. These meanders result when the western boundary current overshoots the latitude of zero wind-stress curl. This article shows that the rapid decay of the meanders of eastward currents can be related to the effect of the meridional shear of the current. -from Authors
