In tropical northern Panthalassa trade winds created westward flows while equatorward flows were created by westerlies at higher latitudes. Consequently, trade winds moved water away from Gondwana towards Laurasia in the northern Panthalassa Equatorial Current. When the western margins of Panthalassa were reached intense western boundary currents would form the Eastern Laurasia Current. At mid-latitudes the North Panthalassa Current would bring the water back east where a weak Northwestern Gondwana Current would finally close the gyre. The accumulation of water along the western margin coupled with the Coriolis effect would have created a Panthalassa Equatorial Counter Current.
