Numerical study on residual current and its impact on mass transport in the Hangzhou Bay and the Changjiang Estuary Ⅱ. Residual current and its impact on mass transport in winter

摘要

Some observational characteristics of residual current and mass transport in the Hangzhou Bay and the Changjiang Estuary in winter are analyzed. The residual current and its impact on mass transport are simulated with a 3 - D joint model for the Hangzhou Bay and the Changjiang Estuary, in which the impacts of river flux, wind, baroclinic pressure gradient (BPG), background current in the East China Sea and tide (including M2, S2, K1 and O1) are taken into account. Based on these studies, further simulations are made to analyze the dynamical mechanisms of the observational characteristics.
