本文以上海港的潮汐预报方法为例,阐述了适用于河口及我国沿海其他浅水港口潮汐预报的一种综合性方法,它包括对天文潮、增减水及其综合水位的预报方法与效果问题的研究等。 上海港扼长江口、濒东海之滨,潮汐属非正规半日浅海潮,常受台风、寒潮和长江径流等水文气象因素的影响,航道水深较浅,潮汐水流情况复杂。近十多年来,通过实践,逐
In this paper, a tidal forecast method for Shanghai Port is taken as an example to illustrate a comprehensive method for tidal forecasting applied to the estuaries and other shallow water ports along the coast of China. The method includes the forecasting methods and effects of astronomical tides, water changes and their integrated water levels Research and so on. At the estuary of the Yangtze River in Shanghai, on the coast of the East China Sea, the tide is an informal half-day shallow tide, often affected by hydrological and meteorological factors such as typhoon, cold current and runoff of the Yangtze. The water depth of the channel is shallow and the tidal flow is complicated. Over the past decade or so, through practice, by
