Abstract

Abstract

The Taiwan Warm Current(TWC)and the Tsushima Warm Current(TSWC)flow northward over the shelf in the East China Sea(ECS).Some previous studies consider them as a Taiwan-Tsushima Warm Current(TTWC)System.It seems that the TWC is dominant in the TTWC system because it is located at the "upst ream" region of the whole system.In this paper,however,we find that the TSWC is more important in the TTWC system.Using a three-dimensional baroclinic model,we conduct several experiments to discuss the dynamic relationship between the TWC and TSWC.The results show that the TWC has little effect on the TSWC,while the TSWC has a significant effect on the TWC.We use source-sink driven mechanism along isobaths to explain this phenomenon.The perennial northward flow through the Tsushima Strait pumps the response over the northern shelf in the ECS that gives rise to the TWC.Although the TSWCis located at the "downstream" region,it could induce 0.5 Sv to TWC in annual mean. The possible mechanism can be explained here in terms of energy propagation by topographic waves.
