摘要
利用常规探空资料， 选取１９９３－１９９５年冬、 春季节中１０个昆明准静止锋典型个例作了合成计算， 分析了昆明准静止锋的结构。研究结果表明， 锋面呈准南北向， 平均位于１０３．５°～１０４°Ｅ附近， 垂直高度约７００ ｈＰａ。受云贵高原阻挡作用的影响， 昆明准静止锋低层的温度场、 湿度场和风场等的结构与一般冷锋有明显差异。
By using the observed data, ten canonical cases of Kunming quasi－stationary front(KQSF) during 1993－1995 in winter and spring seasons are studied. The results show that the KQSF appears as a quasi－northsouth direction and lies in 103.5°～104°E. It is a shallow weather system with vertical height about 700 hPa level. Because of influence of Yunnan and Guizhou Plateau, KQSF’s structure is different from a general cold front in temperature field, humidity field and wind field in the low layer, etc.
