【摘要】 以整个东中国海为计算域,采用64个天文分潮控制外海边界,用台风中心气压、最大风速为参数,建立球面坐标系下平面二维风暴潮数学模型,模拟风暴潮与天文潮的耦合流场。数学模型采用改进的ADI法求解,以9711号台风为例,对风暴潮数学模型进行了风暴潮增水验证,数值模拟结果与实测值符合良好。更多还原

【Abstract】 A two dimensional numerical model is built to simulate storm surges in the East China Sea.In this model,64 harmonic constituents are used as open water bound condition.Storm is simulated based on typhoon center pressure and maximum wind velocity.Double sweep implicit scheme method is adopted to calculate storm surge equations based on sphere coordinate systems.The storm surges caused by Typhoon Winnie is well simulated by this model.更多还原
