East China Sea response to tropical cyclones

The response of the East China Sea (ECS) to a tropical cyclone (TC) is studied with a two-layer nonlinear primitive equation ocean model. Numerical experiments indicate that there is rightward bias in ocean response to a moving TC. The initial middle layer (ML) depth and stratification intensity have substantial impact on the changes of SST and ML depth. The initial ML depth has large effect on the value of the current, whereas the initial stratification intensity has slight influence on it. The distribution of ECS ML depth, especially the special ocean thermal structure on the continental shelf facilitates the drop of SST. The simulation results of ocean response to Typhoon 7002 are fairly consistent with the observation data.
