摘要： 热带气旋、寒潮与大雾是影响长江口及其邻近海域港口、航道及航运安全的主要灾害性天气.本文通过收集和分析文献资料，给出影响长江口及其邻近海域的热带气旋、寒潮和大雾的特征.影响长江口及其邻近海域的热带气旋平均每年有2.3次，8—9月是高发季节；寒潮平均每年有3.15次，主要发生在秋末、冬季和初春；大雾日年平均达50~60 d，主要集中在3—7月.并通过SWAN模型，分别计算热带气旋和寒潮天气作用下在横沙浅滩及其邻近海域的波高分布.

Abstract: Main disastrous weather which affects harbor, navigation channel and shipping are those ones with tropical cyclones, cold fronts and dense fogs. In this paper, the features of main disastrous weather influencing Yangtze Estuary and adjacent waters were quantitatively brought forward by summarizing the correlative literature and research reports. On the statistically average, there are 2.3 tropical cyclones every year, August and September were high-occurrence months；3.15 cold fronts, occurred mainly in late autumn, winter and early spring；50-60 day dense fogs, happened mostly from March to July. In addition, the wave distribution of the Hengsha Shoal and adjacent waters induced by the tropical cyclone and cold front were respectively calculated by use of SWAN model.

Key words: Yangtze Estuary, tropical cyclone, cold fronts, dense fog, wave
