本文基于1976—2006年国家标准断面（大连—成山头）调查资料，结合 ECMWF 气温、风速以及辐射等再分析资料，研究了北黄海冷水团的低温中心以及北部锋面的年际变化规律，并对其与气候年际变化信号的关系做了相关性分析以及 EOF 分析，研究了影响北黄海冷水团的诸多因素。研究结果表明，北黄海冷水团及其北部锋面强度存在明显的年际变化特征，北黄海冷水团中心最低温度具有升温趋势，北部锋面强度具有减弱趋势。分析发现，前冬海温，当地气温，经向风场以及辐射通量都对来年北黄海冷水团的强度存在影响，东亚冬季风的年际变异是影响北黄海冷水团温度年际变化的主要机制，El Nio、La Nia 事件成熟期滞后于北黄海冷水团最低温度的相对低值、高值出现，ENSO 通过与东亚冬季风的相互作用与北黄海冷水团相联系。

Based on national standard section (Dalian-Chengshatou)survey data from 1976 to 2006 and combined with the ECMWF reanalysis data such as temperature,wind speed and radiation,this paper studied interannual vari-ation of the low temperature center and the northern front of Northern Yellow Sea Cold Water Mass,did some cor-relation analysis about the relationship between Northern Yellow Sea Cold Water Mass and interannual climate sig-nals,and studied the factors affecting the temperature of Northern Yellow Sea Cold Water Mass.The results show that the lowest center temperature and the northern front of Northern Yellow Sea Cold Water Mass both have ob-vious interannual variation characteristics.The lowest center temperature Northern Yellow Sea Cold Water Mass has a warming trend,and the northern front exists interannual variability of weakening trend.The winter sea tem-perature,winter air temperature,meridional wind field and radiation flux has certain influence on the strength of the cold water mass of the next year.Influence of interannual variation of East Asian winter monsoon is a main mecha-nism of interannual variability of northern Yellow Sea Cold Water Mass temperature.Mature periods of El Nio and La Nia events occur behind events of the relative low and high center temperature of northern Yellow Sea Cold Water Mass.By interaction with East Asian winter monsoon,ENSO associated with northern Yellow Sea Cold Water Mass.
