Also note the presense of topographically trapped circulations, especially in deep regions of Gulf of Mexico and Carribean. These are generally cyclonic. It is possible, that these are explained as topographically rectified flows obtained from varying forcing. We cannot explain everything we see, however. Velocity scale has been reduced again.
Deep currents are generally much less intense.
