Offshore ekman transport

Webb19 aug. 2016 · The alongshore wind in conjunction with earth’s rotation causes Ekman transport, which drives surface waters offshore, thereby resulting in the upwelling. Another process, Ekman pumping takes place as wind stress curl generates ocean-surface divergence or convergence and forces water upward or downward.

The California Current's southward core is located at the upwelling front, as seen in Figure 10.7, and moves offshore with the front as it progresses through the …

WebbAbstract. Two physical mechanisms can contribute to coastal upwelling in eastern boundary current systems: offshore Ekman transport due to the predominant alongshore wind stress and Ekman pumping due to the cyclonic wind stress curl, mainly caused by the abrupt decrease in wind stress (drop-off) in a cross-shore band of 100 km.
