中国南海东部海域气候特征及风浪流极值参数的研究——LAGFD数值模式群的应用

The Study of Climatic Characters and Wind, Wave, Current Extreme Parameters in the East of South China Sea ——The Application of LAGFD Numerical Models

本文采用先进的ＬＡＧＦＤ风、浪数值模式和ＰＯＭ（ＰｒｉｎｃｅｔｏｎＯｃｅａｎＭｏｄｅｌ）三维海流模式对自１９４５～１９９５年间发生并影响南海东部海域的２９９个历史最强热带气旋过程进行数值后报，给出了南海东部部分海域（１９°～２３°Ｎ，１１３°～１１８°Ｅ）中１０００ｍ等深线内６０个点的多年一遇风、浪、流和水位极值，并简要分析了南海东部（１５°～２７°Ｎ，１０８°～１２２°Ｅ）的气候特征，为该海域区域性海洋环境研究与工程开发提供了基础参考数据。

Based on the advanced LAGFD wind, wave numerical model and POM (Princeton Ocean Model) 3 D current model, numerical hindcasts were made of the severest 299 tropical cyclones in history occuring and affecting the east of the South China Sea from1945 to 1995, and the extreme parameters were given of the wind, wave, current and sea level of 60 points within 1000m bathymetric contour in the region(19°～23°N,113°～118°E). At the same time, a brief analysis is made of the climatic characters of the South China Sea (15°～27°N,108°～122°E). Thus the research provides basic data for regional ocean environmental research and engineering design in this region.
