| 摘 要： | 将长江口、杭州湾及其邻近海域作为研究整体,建立该海区的三维Lagrange正压环流的分阶数值模式,综合考虑径流、东中国海背景环流、风应力和M2,S2,O1,K1 4大天文分潮的综合作用,运用"流速分解法"将环流分为正压梯度流、风生流、潮致余流及零阶环流的非线性耦合流等4个分量,模拟了冬夏两季长江口、杭州湾及其邻近海区的Lagrange正压环流结构.结果表明,零阶环流受东中国海背景环流控制;潮致余流是该海区一个重要分量;杭州湾内正压环流主要由风生流和潮致余流控制.

| Abstract: | The Lagrangian circulation in Changjiang Estuary,Hangzhou Bay and their adjacent sea area is simulated with the riverine flow,East China Sea Current,wind,and the major tidal components(i.e.M2,S2,O1 and K1) taken into account.By splitting current method,the four components for Lagrangian circulation,i.e.the barotropic gradient current,wind-driven current,tidal induced current and nonlinear coupling of zero-order circulation,are obtained.This study focuses on the barotropic current field and its seasonal vari... |
