【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.更多还原
