一、前言沿岸上升流区是海洋生物繁殖的良好场所,因此它成为当代物理海洋学的重点研究课题之一。然而目前对它的研究主要集中在平行于海岸的风或流所诱导的上升流,因为这种上升流的范围大、分布广,不仅在大洋的西岸边界区和东岸边界区可找到,而且许多陆架海区也存在。尽管近年来有些学者开始注意到其他原因所导致的上升流,并发表了一些研究成果,诸如强潮流绕过半岛顶端时导致的上升流,气旋式涡旋诱导的上 I. INTRODUCTION The upwelling area along the coast is a good place for marine life to breed, so it has become one of the key research topics in contemporary physical oceanography. However, its current research focuses mainly on the upwelling induced by winds or currents parallel to the coast because of the large and widely distributed upwelling that can be found not only in the ocean’s western and eastern border regions, but also Many sheltered sea areas also exist. Although some scholars in recent years have begun to notice the ascending currents caused by other reasons and have published some research results, such as the ascending currents caused by the strong currents flowing around the top of the peninsula, the cyclonic vortex induced
