why are the hills centers to the west?
why westward intensification?
the coriolis is stronger towards the poles. so east bound water in the N.Atlantic turns to the right (eqautor bound) faster.
this creates a wide broad mass of water moving southward which shoves the hill center to the west.
thus the westward current has less room forcing it faster and deeper.(same reason small narrow inlets have a faster tidal current)
