中文摘要:

在原处,从在西方台湾海峡的 2010 的夏天巡航的数据被用来学习 Jiulongjiang 河羽毛(JRP ) 的空间分发。结果在 2 m 层显示出那, JRP 出口进在喷气形式的西方台湾海峡,与通过厦门海湾(厦门 JRP ) 和通过在 Jinmen 和 Weitou (JinWei JRP ) 之间的隧道的另外一个的一个分支。也到夏天驾驶西南的季风, upwelling 相关的 Dongshan 低温度和在一口喷气形式向东北的高咸度水流动。到某个学位, Dongshan 低温度和高咸度喷气限制厦门 JRP 传播进一步近海并且拖 JinWei JRP 向东北同时。同时,一个陆上的溶解有机物(DOM ) 分发模型根据在热力学和统计物理的分子的碰撞理论被使用分析中等分辨率成像分光辐射函数(MODIS ) 混浊数据。到 MODIS 混浊数据的理论模型的关联系数到达 0.96 (在信心的 95% 水平重要) 。结果为混浊分发特征澄清动态机制。它是在在沿海的水里在混浊可变性起一个明确的作用的宏规模的咸度。这建议导出卫星的混浊数据能被用作指示物显示出 JRP 的传播模式。从 2003 ~ 2011 基于混浊数据,我们断定有 JRP 的四个主要传播模式[出版摘要]

英文摘要:

In-situ data from the summer cruise of 2010 in the west Taiwan Strait are used to study the spatial distribution of the Jiulongjiang River plume (JRP). The results show that in the 2 m layer, the JRP debouches into the west Taiwan Strait in the form of jets, with one branch through the Xiamen Bay (Xiamen JR_P) and another through the channel between Jinmen and Weitou (JinWei JRP). Driven by the summer southwesterly monsoon, the upwelling-related Dongshan low temperature and high salinity water flows northeastward in the form of a jet as well. To a certain degree, the Dongshan low temperature and high salinity jet restricts the Xiamen JRP from spreading further offshore and drags the JinWei JRP northeastward at the same time. Meanwhile, a terrestrial dissolved organic matter (DOM) distribution model on the basis of molecular collision theory in thermodynamics and statistical physics is applied to analyze the Moderate Resolution Imaging Spectroradiometer (MODIS) turbidity data. The correlation coefficient of the theoretical model to the MODIS turbidity data reaches 0.96 (significant at a 95% level of confidence). The result clarifies the dynamic mechanism for the turbidity distribution characteristics. It is the salinity in macro-scale that plays a decisive role in the turbidity variability in the coastal water. This suggests that the satellite-derived turbidity data can be used as an indicator to show the spreading patterns of the JRP. Based on the turbidity data from 2003 to 2011, we conclude that there are four main spreading patterns of the JRP.
