山东半岛北及东沿岸海域冬季的逆温跃层及其与深底层逆流的关系

Inversion Thermocline in Coastal Region North and East of Shandong Peninsula in Winter and Its Relation to Deep-Bottom Counter Current

引用《渤海、黄海、东海海洋图集——水文》分册中有关逆温跃层分布变化图幅以及海流和温、盐度历史资料 ,指出山东半岛北及东沿岸区域冬季出现的逆温跃层现象与这里冬季潜伏于深底层暖流水有密切关系 ,并进一步认为围绕山东半岛北及东沿岸海域冬季的海水交换可能呈 2层模式 :在上层 ,低温、低盐的沿岸水自西向东南下 ;在深底层 ,相对高温、高盐的逆流水北上自东向西有直逼渤海海峡南部的势头。

Based on the monthly distribution maps of the inversion thermocline from 'Marine Atlas of Bohai Sea, Yellow Sea, East China Sea——Hydrology' and historical data of current, water temperature and salinity, it is shown that the inversion thermocline phenomenon occurring in the coastal region north and east of Shandong Peninsula and adjacent waters in winter has a close relation to the warm current water residing in deep bottom layer there in winter. It is further considered that the water exchange pattern in the coastal region north and east of Shandong Peninsula in winter may be of two layers: the cold and less saline coastal water in upper layer flows from west to east and then southward, while relatively warm and more saline water in deep bottom layer flows northward as a counter current and then westward to approach the southern Bohai Strait.
