| 摘 要： | 根据干绝热曲线法求算最大混合层厚度（MMD）的理论,使用呼和浩特市1956年11月至2009年3月逐日的常规气象观测资料,计算并分析了呼和浩特城区最大混合层厚度的时间变化特征。从月平均值的年变化看,12月最低（993m）,5月份最高（2874m）。旬平均值的年变化趋势基本上与月平均值的年变化一致。当呼和浩特地区日平均风...

| Abstract: | Using daily meteorological data of Hohhot observed from Nov.of 1956 to March of 2009,the changes of maximum mixing depths(MMD) in Hohhot were calculated and analyzed by applying dry adiabatic curve method.According to the annual change of monthly averages,the minimum value(993 m) and maximum value(2874 m) appeared in December and May respectively.The annual changes of ten-day averages were similar as that of monthly averages.The MMD changed with daily average of wend speed.Actually,when the daily average of... |
