| 摘 要： | 利用合成分析方法，对大连地区1960--2000年冷暖冬年冬季的环流形势进行了对比分析。结果表明：在冷暖冬年冬季，海平面气压距平场、500hPa高度距平场、300hPa纬向风距平场都存在着显著的差异，其中蒙古高压、极涡的位置、面积、强度及东亚西风环流指数、极锋急流差异都显著，说明极锋急流、极涡、乌山脊、东亚大槽及蒙古高压等都是影响大连冬季气温异常的关键系统。

| Abstract: | The atmospheric circulation patterns in cold and warm winter years of Dalian during the period of years 1960-2000 are discussed in this paper based on the circulation composite analysis in nine warm and eight cold winters. The results show that there are significant differences in their SLPA fields, height anomaly fields at 500 hPa and zonal winds anomaly fields at 300 hPa. Moreover, it is found that Mongolia High, East Asian Trough, Polar Front Jet and the location, area and intensity of Polar Vortices are notable different, which interpret Polar Front Jet, East Asian Trough and Mongolia High have an important impact on winter temperature abnormality of Dalian. |
