Western boundary currents flow deeper and stronger than eastern boundary currents. However there is no precise boundary that separates the two regions. Similar to the return flow in a household heating system these currents transport colder waters into the tropics where they are heated and transported poleward in the western boundary currents. The equatorward flow of relatively cold water in eastern boundary currents also contributes to the poleward energy flux. Because the top of the hill formed within a rotating gyre is closer to the western boundary than the center of of the gyre the western boundary currents of subtropical gyres are faster narrower and
