我国潮汐潮流区域预报的发展

Development of Tide and Tidal Current Regional Prediction in China

简要回顾了我国潮汐潮流区域预报的发展过程。1959—1964年期间按前苏联杜瓦宁方法编制的永久潮流表是第一代预报产品,该产品提供了我国近海若干站点5 m层潮流预报资料。1970—1978年期间按方国洪提出的方法而研制的永久预报图表集是第二代预报产品,提供了基本上覆盖我国近海的多层潮流预报资料;这两代产品均以纸质图表为载体。2005—2006年期间方国洪等研制了第三代预报产品,覆盖了我国近海各海区,分辨率达到5′×5,′垂向10层,并可自动内插到任意点和任意水层。同时介绍了三代产品的研发过程及基本原理。

This paper reviews the development of the tide and tidal current prediction eration prediction product was developed in 1959-1964. This product, called the Perpetual China. The first gen- Tidal Current Tables, provided predicted tidal current data at 5 m depth at the same limited stations. These tables were compiled based on the method developed by Дуванин. The second generation prediction product, called the Atlas of Perpetual Tide and Tidal Current Prediction for China Adjacent Seas, was completed during 1970-1978. This product was compiled based on the method developed by Fang Guohong. The atlas covered nearly entire sea areas adjacent to China and provided tidal current data at 5 levels in the vertical. Both the first and second generation products used printed paper as platforms. During 2005-2006 we developed the third generation prediction product. This product covered the entire China adjacent seas, with a resolution of 5＇ ×5＇ and 10 levels in the vertical. The product allowed interpolation to an arbitrary location and level. The development processes and the basic principles are introduced in the present paper.
