摘要

摘要: 本文基于多年月平均水温资料,分析了青岛冷水团的长消过程,并利用气候态月平均大气数据和数值模拟结果,探讨了青岛冷水团的消亡机理。结果表明,青岛冷水团3月出现,4月成型,5月最盛,6月减弱,7月消失;南黄海6-7月间偏南风的增强和温跃层以下反气旋涡的减弱是青岛冷水团消亡的动力机制,而海面净热通量的下传和水平热量的输入则是青岛冷水团消亡的热力机制。

Abstract: In this work, the growing and vanishing processes of the Qingdao Cold Water Mass (QCWM) were studied based on monthly mean climatological sea temperature data in the South Yellow Sea. And then, the extinction mechanism for QCWM was also examined using the meteorological data and the numerical simulation results in this study area. The results showed that the QCWM appears in March, has stable pattern in April, is biggest in its area in May, becomes small in its area in June and vanishes in July. During June to July, the strengthening of southerly winds and weakening of the anticyclonic eddy below the thermocline are the dynamic mechanism for the QCWM extinction, while the downward transfer of sea surface solar radiation and horizontal heat input are the thermodynamic mechanism of the QCWM extinction.
