摘要
基于FVCOM数值模式,建立了适用于宁德海域的三维风暴潮数值模型,其中台风气压场采用高桥公式和藤田公式嵌套的方法,台风风场则通过台风梯度风风场和移行风场两个矢量场叠加,并考虑台风移行产生的风场以及梯度风到海面风的订正。通过0713和0716号超强台风过程的数值模拟验证,此模型能够较好地模拟出宁德海域的天文潮、台风过程的风、气压以及风暴潮增水。
three-dimensional storm surge numerical model for Ningde coastal region was established based on the FVCOM.The pressure field was calculated by the Takahashi formula and Fujita formula nesting method.Considering the correction to the sea surface,the wind field was calculated through the gradient wind field and move wind field.Through the numerical simulation of the super typhoon 0713 and 0716,the results showed that the model can successfully simulate the astronomical tide,typhoon wind,air pressure and storm surge in the Ningde coastal region.
