It should also be noted that coastal upwelling seasonally tends to increase or decrease surface salinity depending on whether salinity increases or decreases with depth. For example, in the California Current, upwelling causes an increase in surface salinity whereas in the Peru and Benguela Currents its effect is to decrease surface salinity. C.

Flow Surface ocean flow is predominantly in the sense of the prevailing winds, which are anticyclonic about the mid-ocean highs and cyclonic about the sub- polar lows. This similarity between atmosphere and ocean circulation is, of course, more than coincidence, and many of the basic features of the eastern currents are contained in the general theory of the wind-driven circulation 160° 140° 120" 100* SO'. 160° 140° 120° 100° 80°.
