摘    要:利用2006~2007年夏冬春秋4个季节北黄海的大面调查资料,分析了4个季节北黄海温度和盐度大面以及典型断面分布特征,得出以下结论:2007年冷水团势力范围强于2006年,北黄海冷水团的形成受地形影响.黄海暖流冬春季较强,冬季最强,夏季最弱,秋季开始形成.鲁北沿岸流冬季最强,春季减弱,夏秋季消失,但夏季鲁北沿岸存在冬季鲁北沿岸流水的残余体,即鲁北沿岸水.辽南沿岸水4个季节都以低盐为特征,除夏季低盐中心位于庄河口外,其它3个季节低盐中心均位于调查区域的东北角.渤海与北黄海之间的水交换4个季节都存在.春季,断面盐跃层形成滞后于温跃层;秋季,断面盐跃层消失滞后于温跃层.

关 键 词:北黄海  温盐  黄海冷水团  黄海暖流

Abstract:By using the survey data of the North Yellow Sea(NYS) in the four seasons 2006~2007, the plane and vertical distribution characteristics of temperature and salinity of the NYS in the four seasons are analyzed. The result shows that the area of the Yellow Sea Cold Water(YSCW) in 2007 is larger than that in 2006 and the formation of YSCW is largely affected by topography. The Yellow Sea Warm Current(YSCW) is strong in winter and spring, which the is strongest in winter, and the weakest in summer. It begins to be formed in autumn. The Lubei Coastal Current is the strongest in winter. It begins to be weakened in spring, and does not exist in summer and autumn. There is remnant of the winter Lubei Coastal Current Water in the northern coastal area of Shandong in summer, and it is the Lubei Coastal Water. The Liaonan Coastal Water is characterized by low salinity in the four seasons. Except that, and the low salinity center is located near the Zhuang River mouth in summer, and the low salinity centers in other seasons are all located northeast of the survey area. There is water exchange between the Bohai Sea and the NYS in all the four seasons. In spring the haloclines are formed later than the thermoclines, and in autumn the haloclines disappear later than the thermoclines.
Keywords:the North Yellow Sea  temperature and salinity  Yellow Sea cold water  Yellow Sea warm current
