中文摘要： 2007年以来，黄海浒苔绿潮事件频发，规模时大时小，规律难于捉摸，使包括苏北海域在内的黄海西南部浒苔活动海域成为研究的热点，也改变了我们对该海域动力学的传统认识。本项目计划以大规模绿潮发生、发展的典型季节—春夏季为研究时段，以黄海西南部浒苔活动海域为重点研究区域开展研究，建立能抓住辐射状沙脊群地形特征的区域海洋数值模型，开展浒苔绿潮相关动力学研究。模型将考虑潮汐、风和斜压效应，结合现场观测和遥感资料，以揭示苏北浅滩潮流和潮致余流的精细结构，分析黄海西南部沿岸流的特征，阐述春夏季影响浒苔生长的温度和盐度的分布特征与变化规律，探讨春夏季影响浒苔运移路径黄海西南部沿岸流的形成机制，为黄海西南部海域生态环境的预测和改善提供科学依据。

英文摘要： Since 2007, green tide has occurred frequently in the Yellow Sea. Uncertain scales and unpredictable regularities of green tide make South-western Yellow Sea including the North Jiangsu Sea become a hot area of research. And it is also give us an opportunity to change the traditional understanding on dynamics of sea areas. This project plans to study hydrodynamics in South-western Yellow Sea during the typical seasons (spring and summer) of massive green tide. A regional marine numerical model which could capture features of the radial sand ridge will be used to study the related dynamics of green tide. The model will include tide, wind and baroclinic effects, combined with field observation and remote sensing data to focuses on the following scientific topics as: revealing fine structure of tide and tide-induced residual current in the Subei Shoal, analyzing features of coastal current in the Southwestern Yellow Sea, illustrating spatial and temporal variation regularities of factors in affecting the growth of green tide like as temperature and salinity and so on. In conclusion, this project can provide scientific basis for predicting and improving the ecological environment in the Southwestern Yellow Sea.
