摘    要:利用北京地区冬春季节逐日定时地面常规观测资料,使用修正的Pasquill分类法计算了该地区大气稳定度相对值序列,并在此基础上分析了大气稳定度月际变化、日变化等分布特征,划分出若干持续时间较长的长稳定过程。

关 键 词:Pasquill分类法  大气稳定度  长稳定过程  北京地区  冬季  春季  月际变化  日变化

Abstract:According to the daily and hourly data of recent surface conventional observation in winter and spring over Beijing, the relative value series of atmospheric stable degree was caculated with revised Pasquill classified method.Based on the relative value series of atmospheric stable degree,the distribution characteristics of atmospheric stable degree are analyzed in intramonth and day.Several long stable processes which persisted for a longer time are divided.
Keywords:Beijing area  atmospheric stable degree  long stable process
