Upwelling In Low Latitudes

Figure 5 9 is a schematic map show ing the different upwelling regions of the eastern tropical Atlantic. A comparable map could he draw n for the eastern tropical Pacilic

Figure 5.9 The positions of the various upwelling aieas in the tropical Atlantic, in relation to the eastward subsurface flow m the equatorial current system (the westward-(towing North and South Equatotial Currents have been omitted for the sake uf clarity). The upper part ot the map may be compared with Figure 4.38. Note that to the north of the Cape Blanc zone of year-round upwelling there is another zone ol seasonal upwelling (off the map!
