我国海洋普查首先观测到广东近海冬季存在一支逆风海流,后定名为“南海暖流”。其后,管秉贤(1978)根据地转流的计算结果,阐述了这支海流的若干特性,认为这支逆风海流与太平洋副热带逆流有某些相似之处。本文作者之一,根据北纬18°断面的历史资料,指出南海北部陆架外冬季有一辐聚区存在。但是冬季这支逆风海流究竟与寒潮大风有何联系,还没有进行深入研究。
First of all, the ocean census of our country has observed the existence of an upwind current in the coastal area of Guangdong in the winter, and is named as “the current of the South China Sea.” After that, Guan Bingxian (1978) explained some characteristics of this current based on the calculation of the current diversion and concluded that there are some similarities between this adverse typhoon current and the Pacific subtropical countercurrent. According to the historical data of 18 ° North latitude, one of the authors of this paper points out that there is a convergence zone outside the continental shelf in the northern South China Sea in winter. However, in winter, what is the relationship between this adverse typhoon current and the cold wind? No in-depth study has yet been conducted.
