摘　　要：利用所收集的1957～1996年这40年期间在珠江口纵深一线引起较大增水的56次热带风暴(含台风)及其增水的资料,分析了台风暴潮沿珠江河道上溯运动的问题。本文从这些风暴登陆的地点及频率、在珠江口纵深引起最大增水的时刻、这些风暴路径离珠江口的距离、珠江口纵深各站的最大增水比较、这些风暴增水和登陆时的风暴最大风速及中心气压的关系等方面讨论了有关的问题,得出了台风暴潮沿珠江河道上溯情况的概貌,为进一步深入分析有关机理问题打下了基础。In this paper, by using the data of 56 tropical storms (including typhoons) occurring in 1957~1996 which cause large setup of water along the Pearl River, the problem of the upstream going of the tropical storm surge is analyzed. Based on the following statistics; the landing positions and frequencies of these storm surges, the time of the maximum setups of water along the Pearl River, the distances between the paths of these tropical storms and the Pearl River estuary, the comparison of the maximum setup of water in different stations along the Pearl River, and the relations of the maximum setup of water and the maximum wind speed of storm or the central pressure of storm when it is landing, appropriate problems are discussed. The feature of upstream-going tropical storm surges along the Pearl River are outlined, which can be a base for further study of the mechanism on this topic.
