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
