Explanation:
In addition to differences in temperature, the poleward moving warm currents off the east coast of continents tend to be narrower, deeper, and faster than the equatorward moving cool currents flowing off the west coast of continents. This phenomenon is called western intensification because it occurs on the western side of the sub-tropical gyres. There are a number of reasons for it – the main being Coriolis effect. The Coriolis effect is greater
in higher latitudes, the eastward moving high latitude current flow is deflected back toward the equator more strongly than the westward moving equatorial current flow which is deflected toward the poles. This means that the cool water is slowly flowing back toward the equator across much of the eastward-moving high latitude currents, whereas polewardmoving warm currents are confined to a fairly narrow zone off the east coasts of continents.
