Numerical Simulation of Wind Wave in Bohai Sea Induced by Cold Wave

Abstract

This paper using WRF mesoscale atmospheric model, the reanalysis wind field data provided by ncep global forecast field as the initial condition and boundary condition with time, calculated the wind field with sufficient precision, provided the driving wind field for the wave numerical calculation, calculated the corresponding wave field with model SWAN, and simulated the wind wave process caused by a cold wave wind in the Bohai sea area from 5 to 7 November 2015. The calculated model was verified by the measured wind and waves data at the stations of Huanghua and Dongying. The results show that the simulation values of wind and wave elements are in good agreement with the measured values. The model can reproduce the characteristics of wind and wave distribution during the cold tide in Bohai Sea.
