| 摘 要： | 兰州市城区空气污染严重与其特殊的大气边界层密切相关。利用兰州市城区现有大气边界层探测资料,采用多种稳定度参数计算方法,统计分析了该市大气层结稳定度的时空分布规律及其与天气形势的关系,发现兰州市城区冬季大气稳定边界层日间存在发生或发展的特有现象,并探寻了其形成机制,从而为兰州市开展空气污染预报提供可靠的理论依据.

| Abstract: | The serious ai r pollution in Lanzhou city is closely related to the property of atmospheric boundary layer.Discusses the spatiotemporal distribution of the air stability in Lanzhou city and its relation to the weather types, applying 5 statistical methods based on the observed boundary lay er parameters.It's show n that the stable atmospheric boundary layer can occur and develop at day time in winter in Lanzhou city.In addition, the mechanism is studied for further application in the air pollution forecast in Lanzhou city. |

| Keywords: | Lanzhou city stable boundary layer spatio temporal variety |
