4.3 The Tropical Ocean Circulation
235
Fig. 4.3.10 (a) Annual cycle of surface zonal currents from ship drift between 1°S and 1°N in the Indian Ocean, from
Reverdin (1987); (b) Surface zonal currents from the GFDL model examined by Visbeck and Schott (1992) (see text);
(c) Annual mean surface flow from buoy drifts (from Molinari et al., 1990a). Note that currents extend outward from
the dots, so that (for example) currents along the equator are eastward.
