| 摘 要： | 本文利用趋势分析、突变分析以及小波分析等方法对近42 a辽宁南部（大连）和北部（沈阳）第一对流层顶高度变化特征进行分析和比较，结果表明：近42 a，辽宁第一对流层顶高度除冬季以外其它三季和年呈下降趋势，南部地区的降幅明显大于北部；多年均值的年变化表现为在夏季最高、春秋季次之、冬季最低，各个季节南部高度值普遍高于北部；年际变化幅度在夏季最大，除冬季外，南部大于北部；发生气候突变的时段基本上都在1970年代中期前后；周期变化特征时空差异较大。

| Abstract: | The variation of the first tropopause height (FTH) from 1964 to 2005 over Shenyang in the north of Liaoning province and Dalian in the south of Liaoning province was analyzed by the trend analysis and the abrupt change analysis as well as wavelet analysis. The results show that the seasonal and annual variations of the FTH over Liaoning province decrease in the recent 42 years, except in winter. The decreasing amplitude in the south of Liaoning province is greater than that in the north. According to the multi-yearly averages of the FTH, the highest value appears in summer, followed in spring and autumn. The lowest one is in winter. Moreover, the FTH in the south is higher than that in the north in different seasons. The inter-annual change ranges of the FTH are larger in summer, and the ranges in the south are larger than that in the north, except in winter. The climatic abrupt change appears in the metaphase 1970s. In addition, the temporal and spatial differences of cycle variations of the FTH are obvious. |
