读一篇关于南海温跃层变化的文献时候，提到“Due to the upper Ekman transport caused by monsoon over the SCS, the thermocline slopes upward(downward) in winter(summer) from northwest to southeast, but there is no pileup of upper warm water along the monsoon direction. ” 请问，Ekman transport是什么？ |

Ekman Transport, part of Ekman motion theory first investigated in 1902 by Vagn Walfrid Ekman, is the term given for the 90° net transport of the surface layer (the layer affected by wind) by wind forcing. This phenomenon was first noted by Fridtjof Nansen, who recorded that ice transport appeared to occur at an angle to the wind direction during his Arctic expedition during the 1890s. It is the net motion of fluid as the result of a balance between Coriolis and turbulent drag forces. [Followed the wikipedia] 海洋科学课上貌似学过，不过我这地质狗早还给老师了。 具体的公式和示意图可以直接google或者wikipedia。。。 |
