摘要
本文概括了近几十年来,关于德里克海峡附近绕极流研究的进展.这些研究主要以实际观测资料为基础,说明了德里克海峡附近海洋锋面分布和绕极流的体积输运。其中,主要的海洋锋面有:亚南极锋(SAF),极锋(PF)和陆缘水边界(CWB);而德里克海峡绕极流的体积输运则代表了太平洋和大西洋两大洋之间通过德里克海峡的水量交换。读者可通过本文加深关于德里克海峡锋面成因和绕极流机制的理解。
For past dozens of years the researches on the circumpolar current at the Drake Passage, which links the Pacific and Atlantic off the Antarctic are reviewed. Most researches, based on observatory data, elaborated the frontal distribution and circumpolar water transportation at the Passage. The chief fronts studied are sub-Antarctic front (SFA) , polar front (PF) and continental-water-boundary (CWB). The water transportation by the circumpolar current at the Passage reflects the exchange volume between the Pacific and Atlantic. The causes of frontal formation and the mechanism of circumpolar current are aporoached.
