| 摘 要： | 用国家标准ＧＢ／Ｔ１３２０１中规定的方法计算了成都１９８０～１９９１年的大气混合层厚度，并用于绝热法和罗氏法计算了成都１９８８年的大气混合层厚度，结果表明：成都大气混合层厚度逐年变化不大，有明显的季节变化和日变化，大气稳定度是决定混合层厚度的主要因子。３种方法的对比表明：罗氏法比国家标准法更接近干绝热法的结果，因此在有常规地面观测资料的地方用罗氏法更准确些。

| Abstract: | The thickness of atmospheric mixed layer above Chengdu for the past 12 years is calculated conformable to the National Standard GB/T13201-91 and that of the year 1988 is calculated by using Nozaki method and dry adiabatic method. The results show that the seasonal and diurnal changes of the thickness of mixed layer above Chengdu is obvious and the atmospheric Stability is an important factor in determining the thickness of mixed layer and that calculation by Nozaki method is mote approximate to that by dry adiabatic method than by national standard method and is more accurate in routineuse. |
