南沙暖水域位于南海南部,濒临赤道,处于Walker环流上升区和南北半球气流交换的通道上,是南海海温较高的区域,也是海气相互作用的敏感地区。热带海域海洋及大气环流的变化对该海域海温的变化有着重要影响。 以往的研究表明,南海海温与赤道中、东太平洋水温和西太平洋副热带高压关系密切 Located in the southern part of the South China Sea, the Nansha warm waters are on the verge of the equator. They are located in the Walker circulation up-zone and the air exchange exchange between the northern and southern hemispheres. They are high in the South China Sea and sensitive to the interaction of the sea-air. Changes in the tropical oceans and the general circulation of the atmosphere have an important influence on the variation of SST in this area. Previous studies show that the SST in the South China Sea is closely related to the equatorial and eastern Pacific water temperatures and the western Pacific subtropical high
