【摘要】 <正>南海是世界著名的季风盛行海域,冬季盛行东北季风,夏季盛行西南季风。东北季风盛行期间,海表层为西南向漂流;西南季风盛行期间,海表层为东北向漂流。由于季风的作用及热盐的影响,因而南海的流场与质量场互相调整适应。夏季南海东北部海水堆积,海面由东北向西南倾斜;冬季则相反。考虑到流场、质量场以及地形作用相互调整和β效应的影响,在等深线密集的那些海区因底形倾斜引起等效β效应可能会产生地形Rossby波。更多还原

【Abstract】 Basing on the potential vortex conservation equation, considering effects of the topographic declination in the west and north of the South Ch ns Sea, conditions that produce topographic Rossby waves in this area are derived, when ourrents flow SW, topographic Rossby wave may occur, whereas when they flow NE, no topographic Rossby wave occurs in these areas. Differences between the winter circulation and the summer one can be explained by the effects of topographic Rossby wave and of topographic forcing.更多还原
