• 摘要：本文利用135个气象站的常规观测资料及改进了的Pasquill-Turner方法,逐站统计了各稳定度出现的年季频率等,并以此将全国划分为6个区域。分别给出了各区域内的各稳定度出现的年季频率,同时给予气候分析。此外,给出了根据我国EL-1型风仪所确定的风向标准差与Pasquill稳定度类别的关系。

• Abstract：Based on routine data collected at 135 weather stations scattered around the country and the stability classification (A-F) scheme developed by Pasquill and Turner, percentage occurrence of each stability class (annual and seasonal) for the stations has been calculated. Taken into consideration of the climatic and geographical conditions, the whole country may be divided into six regions and average percentage occurrence of each stability class has been given for the regions.
