Abstract
Water mass structure in a coastal area is significantly affected by meteorological forcing. Typhoons, in particular, have a great impact on the coastal water environment. The present study aims at numerically investigating the variation process of water mass structure in Ise Bay area under influence of Typhoon 0918 using an Atmosphere-Ocean-Wave-Water Quality coupled model and the four dimensional data assimilation with a tropical cyclone bogus scheme. As a result, the flow structure was found to be significantly changed by the effect of the typhoon, such as the formation of a vertical circulation flow due to strong winds. Furthermore, the numerical results revealed that the vertical mixing of water column was induced by the vertical circulation flow, resulting in the disappearance of hypoxia.
