摘要
基于W0A东北亚海1/10。温盐统计数据产品、海洋水文图集和历史海洋调查相关研究成果,系统研究了东北亚海温度盐度结构主要特征;春季和夏季,黄海东西沿岸存在温度低值中心;描述和定义了黑潮右侧次表层伸向西南方向的“黑潮逆流冷舌”;研究了东北亚海主要流系和部分海洋中尺度现象(海洋涡旋、海洋锋、上升流、长江冲淡水等)引起的温度盐度结构特征。日本海40°N附近海洋温度锋一年四季都比较强,中国东海海面温度锋在冬季和春季比较强。台湾东北冷涡和日本以南超级暖涡附近是温度极值中心。该研究成果为东北亚海海洋水文环境保障提供技术支撑。
China marine powerful nation strategy need more marine infonnation products.Based on the Regional Climatology of the Northeast Asian seas(1/10°),ocean atlas,and the history survey study results,the main characteristics of the ocean temperature and salinity in the Northeast Asian sea are studied.There are cold patches in the Yellow sea western and eastern coast in spring and summer.The Kuroshio subsurface counter current cold tongue at the right side is studied and defined.The main ocean current and ocean mesoscale phenomena(ocean eddies,ocean fronts,coastal upward current,Changjiang River Diluted Water),and the coherent temperature and salinity characteristics are studied.The temperature front is very strong in the Japan sea 40°N in four seasons.The East China sea temperature front is strong in winter and spring.This result can be the theory basis for the marine environmental information service.
