摘要
为提高风暴潮的模拟精度,将台风风场模型与NCDC背景风场进行叠加,考虑天文潮对风暴潮的影响,应用二维水动力模型MIKE21模拟了1210号台风"达维"(Damrey)期间江苏海域的风暴潮增水。比较不同气压场公式及不同最大风速半径公式构造出的风场模型对模拟结果的影响,选取最优组合分析台风对江苏海域流场的影响。结果表明,模型能较好地模拟台风期间的风暴潮增水,利用Holland气压场公式与江志辉最大风速半径公式模拟风场的计算结果更符合实测值。
In order to improve the simulation precision of storm surge, we superimpose typhoon wind field and NCDC background winds together and also consider the influence of astronomical tides on storm surge.By using the two dimensional hydrodynamic model MIKE21, the storm surge in Jiangsu sea area is simulated during No. 1210 typhoon Damrey period. The influences on simulation results by applying different formulas of pressure flied and radius of maximum wind speed are discussed, and the best combination to analysis the flow flied is selected. The simulation results show that the storm surge caused by typhoon can be simulated well by this model, and the results of the combination of Holland＇s pressure flied formula and Jiang Zhi-hui＇s radius of maximum wind speed agree better with the measured value.
