渤、黄海温度跃层的分布与变化

VARIATION AND DISTRIBUTION OF THERMOCLINE LAYERS IN BOHAI SEA AND YELLOW SEA

依据1976～1988年渤、黄海BT观测资料,分析了渤、黄海的温跃层特性。渤、黄海温跃层一般从3月开始形成,以后逐渐加强,最强温跃层渤海出现在7月,黄海出现在8月。最大跃层强度渤海为5.6℃/m,北黄海为6.6℃/m,南黄海为7.7℃/m,强跃层区分布在渤海中央、北黄海中部和青岛外海。温跃层消失时间,渤海一般为11月,北黄海为12月,南黄海则为1月。

Based on the data of the bathythermograph (BT) observe'd from 1976 through 1988, the thermocline characteristics of the Bohai Sea and Yellow Sea are analysed. The thermocline layers of the areas usually began to appear in March, then gradually intensified and the greatest value of intensity were seen in the Bohai Sea in July ' and the Yellow Sea in August. Strong thermoclines were in central part of the Bohai Sea, central part of northern Yellow Sea and the area offshore of Qingdao. The thermocline in the Bohai Sea decayed earlier than in the Yellow Sea. The disappearance was generally in December for the Bohai Sea, November for northern Yellow Sea and January for southern Yellow Sea.
