尽管出现上升流的海区仅占海洋总面积很小的一部分(约千分之一),并且上升速度也很小(约10~(-5)—10~(-2)cm/s),但上升流这一海洋现象却引起了海洋科学工作者的极大兴趣。上升流把深层水带到海面,使该海区海面温度明显降低,从而直接影响到毗邻的沿岸地区的气候;另一方面,由于含有丰富营养盐的深层水涌升到表层,上升流海区的透光层就成为有利于海洋生物栖息、繁殖的场所,因而它一般都是渔场所在地。
Although the sea area where updrafts are present accounts for only a small fraction of the total ocean area (about one in 1,000th) and the rate of rise is small (about 10 -5 -10 -2 cm / s) The oceanic phenomenon of upwelling has aroused great interest among oceanographers. The ascending current brings the deep water to the sea surface, causing the sea surface temperature in this sea area to decrease obviously, thus directly affecting the climate of the adjacent coastal areas. On the other hand, due to the deep water surge with rich nutrients rising to the surface, The light layer has become a place conducive to habitat and reproduction of marine life, so it is generally located where the fisheries.
