大亚湾海水混合交换特征

STUDY ON THE PROCESS OF SEA WATER EXCHANG IN DAYA BAY

本文研究了大亚湾海水垂直与水平交换特征。结果表明:由于夏季表层水升温和粤东沿岸上升流高盐冷水入侵,大亚湾海水分层。大亚湾海水垂直循环属于单次混合型。高盐冷水入侵大亚湾的过程变异性很大,变化的时间尺度约15d,抬升速度为1.8×10^(-3)cm/s。

The reasons to cause the sea water of Daya bay to stratify are that the surface water temperature increases in Summer and the cool brine of up welling along the Yue Dong coast intrudes. The vertical circulation of sea water of Daya bay belongs in single mixed type. The varation of process of the cool brine intruding in Daya bay is very great, its time scale is about fifteen days, going up velocity of the cool brine is 1.8×10-3cm/s.
