本文通过历史资料分析:长江上游迳流,黄浦江上游来水、台风以及天文潮对上海港风暴潮的作用,从而说明上海港风暴潮主要是由强台风遇天文大潮所形成。上海港地处长江迳流,太湖来水以及外海潮汐的交汇处,历史上在台风活跃季节曾出现多次风暴潮水位。实际出现的风暴潮h_o=h_p+△h,hp:天文潮予报;△h:由气象或其它偶然性因素引起的随机变量。由於上海港港址所处的特定地理位置,△h部分包含了长江洪峰流量下泄、黄浦江上游来水以及非周期气象潮的作用,现以黄浦公园吴淞站为例,分
Based on historical data, the effect of the typhoon in the upper reaches of the Yangtze River, the incoming water in the upper reaches of the Huangpu River, the typhoon and the astronomy tide on the storm surge in Shanghai Port are analyzed. The results show that the storm surge in Shanghai Port is mainly caused by the strong typhoon encountered by the astronomical tide. Located on the confluence of the Yangtze River inflows, Taihu Lake incoming water and the tidal flats in the open sea, Shanghai Harbor has historically had several storm surges during the active typhoon season. The actual storm surges h_o = h_p + △ h, hp: astronomical trough to report; △ h: random variables caused by weather or other contingency factors. Due to the specific geographical location of the port of Shanghai Port, the △ h section contains the release of the peak flow of the Yangtze River, the incoming water in the upper reaches of the Huangpu River and the auroral tidal cycle. Take Wusong Station of Huangpu Park as an example.
