摘要

青岛冷水团盘踞于山东半岛东南部近海的深底层。它是南黄海西部海域中的一个突出而重要的水文现象。青岛冷水团的存在和变动不仅使南黄海西部的环流结构和水文状况趋于复杂，而且还影响山东近海渔场春汛渔期的早晚和鱼群的集散程度(郑东等，1983；张元奎等，1989)。目前，对青岛冷水团的温、盐特性及其成因早已有研究(郑东等，1983；张启龙等，1996；Zhang et al.，2002)，但有关青岛冷水团的长期变化特征尚未见报道。作者在已有研究结果基础上，利用1959~1995年间的水温资料，对青岛冷水团强度的变化特征进行分析，以期加深对青岛冷水团的认识以及为该海域海洋水产资源的合理开发利用提供科学依据。

Abstract

In this work, using the sea temperature data on the western Yellow Sea during 1959-1995, the main features of long-term, stage and interdecadal variations in Qingdao Cold Water Mass (QCWM) strength were studied by using regression analysis and maximum entropy method. The QCWM'S interannual change and possible causes were discussed using the air temperature data in North China. The results showed that the QCWM strengthened during 1959-1975 and weakened during 1976-1995; and that the stage change in the QCWM'S strength displayed regular low-frequency oscillation. The interannual changes in the water mass strength were associated with the ENSO cycle, and were affected by winter (February) air-temperature changes in the coastal area of the northern Shandong Peninsula.
