摘要: |
本文从海面水温场和水温垂直分布的统计特征,阐述了南海北部存在季节性的上升流。该上升流主要出现在汕头、琼南沿岸近海和湛江港外附近,其成因可能是由夏车西南风使水体辐散及夏季海水涡流的辐散所引起的。 |

A PRELIMINARY APPROACH OF THE UPWELLING FOR THE NORTHERN SOUTH CHINA SEA |
|
Abstract: |
In this paper, the appearance of upwilling for the nor them South China Sea is expounded and analysed through the statistic structures of the temperature fields on the surface and in the sections of the sea. The possible causes of formation of the upwelling are explained mainly in terms of Wind-Driven and Eddy-Driven Upwelling, in other words, there are two types of upwelling in this region. Comparing the speeds and the directions of the sea surface currents against those of the wind in the upwelling area, we find that the Wind-Driven Upwelling in this region is nearly in agreement with the theory of Ekman (1905). |
