Abstract:
Simulated storm surge elevation by the oceanic model is strongly dependent on the wind field, thus the correct simulation of wind field is the important prerequisite. Four typical cases are used to test the impacts of the modified Bohai Sea calculated wind field models on the numerical simulation of storm surges. The hourly Bohai Sea elevation fields before and after the correction are obtained by the numerical model driven by the wind field. Compared to the observed values of Tanggu Station, we can conclude that the simulated results are obviously improved. The simulated extreme values, process curves and the elevation correspond well to the observed values. The accuracy of the calculation results is enhanced significantly after the correction. Results show that by using the appropriate method of sealevel wind field correction, the accuracy of the simulated wind field is enhanced and the oceanic model can simulate the strong storm surge elevation that is close to the reality.
