摘　　要：根据1984年2月-1987年11月期间卫星遥感磁带资料，利用美国全球SST模式反演海表温图像，对黄海区表温及水系（包括流系、冷水带和海洋锋）的分布特征及其季节变动进行分析，分析结果为：黄海区存在暖水系与沿岸水系，冬季构成西部环流与东部环流。黄海夏季表层东西两侧存在两条南北向的冷水带，在冷水带中出现几个低温中心，其中以辽南低温中心持续时间最长（从4月至12月），黄海区海洋锋有冬季型与夏季型之分。Analysis of the distributive characteristics and seasonal variations of the Yellow Sea current system, cold water band and ocean front in winter and summer by using satellite images showed that the warm water system and coastal water system in the Yellow Sea have obvious seasonal characteristics. In winter, the coastal current on both sides of this sea links up from north to south and forms with the warm current of the central area, the West Circulation and East Circulation respectively. In the warm season, in the east side and the west side of the Yellow Sea surface layer are two cold water bands distributing from north to south and some low temperature centres in them. The Liaonan Low Temperature Centre is the lon-gest in continued period (from April to December). It is composed of two low temperature centres: one is formed from winter's remnant water; another is formed from coastal cold water flowing southwards. The ocean fronts of the Yellow Sea can be divided into winter and summer types. The cold water bands are as important oceanic phenomenon in the Yellow Sea as the ocean front.
