近十年德州市秋冬季大气污染气象条件变化分析

Analysis on the changes of meteorological conditions of air pollution in autumn and winter in Dezhou

利用德州市气象站近十年(2008-2017)的气象数据对该市与大气污染相关的气象条件进行统计分析。结果表明,德州市秋冬季空气质量与气象条件明显相关,气象条件差的年份,空气质量也往往较差。2013-2014年以来空气质量的好转除了得益于政府的各项减排措施,气象条件的改善也是重要原因之一。

The meteorological conditions related to air pollution in the city were statistically analyzed using meteorological data of Dezhou Weather Station for nearly ten years (2008-2017). The results show that the air quality in autumn and winter in Dezhou is obviously related to meteorological conditions. In the years with poor meteorological conditions, the air quality is often poor. The improvement of air quality since 2013-2014 is not only due to the government’s various emission reduction measures, but also the improvement of meteorological conditions.
