| 摘 要： | 目前有关"激流"成因的研究不少,但基本处于观测与假说阶段,仍需从更多海流实测资料中继续丰富相关研究。选取南黄海辐射沙脊北部的主要潮汐通道西洋水道为研究对象,利用1980年、2001年和2008年的实测数据分析研究了"激流"的主要特征,并通过建立的二维潮流泥沙数学模型对"激流"的成因进行了初步探讨。研究认为,"激流"与涡旋、风应力无关,特殊地形是其发生的最基本条件之一。

| Abstract: | Increasingly researches on storm current have been done presently; however, favorable solutions to a large amount questions still remain in observation and assumption phases. Therefore, more studies on storm current should be performed according to moremeasurement data of ocean flow.This research focused on the Xiyang Channel, north of radial sand ridges area. Characteristics of the storm current were analyzed based on the measured data (1980, 2001 and 2008). Using a 2-dimensional current-sediment model, further studies on the genesis of storm current were conducted. Results indicate thatvortex and wind stress are not the factors for the genesis of storm currentwhilethe special topographyisone of the essential necessity of storm current origination. |
