Abstract

Abstract

An unstructured grid model based on FVCOM was used to simulate the storm surges in the regions of the Changjiang Estuary, the Hangzhou Bay, the Fujian coast, the Pearl River Estuary, and the South China Sea. Two kinds of typhoon models were compared, i.e. the unsymmetrical typhoon provided by the WRF model and the symmetrical typhoon calculated by using the Fujita formula. Both of these two typhoon models can simulate the storm surge well around the Changjiang Estuary, the Hangzhou Bay, the Pearl River Estuary and the South China Sea, with the unsymmetrical typhoon model producing the results slightly better. For the typhoons crossing the Taiwan Island and then landing along the Fujian coast, the unsymmetrical typhoon by WRF can simulate storm surge far better, since the typhoons in that region are significantly unsymmetrical.
