【摘要】 随着临沂经济的发展,机动车持有量的上升,尾气排放逐渐增加。城市化进程逐步加速,带来了更多的建筑扬尘,再加之以煤炭为主的能源结构类型,这些导致了临沂的区域大气污染现象的发生。空气污染与气象条件有着直接的关系,本文以温度、相对湿度、风向和风速四个气象因素为例,介绍了其2014-2015年的变化规律,分析了临沂的基本气象条件,探究了六种基本污染物与气象因素的相关关系并对2014-2015年冬季的典型灰霾污染天气过程进行48h后向轨迹分析。更多还原

【Abstract】 With the economic development of Linyi, motor vehicle holdings increased, the exhaust emissions gradually increased. The process of urbanization is accelerating, bringing more construction dust, combined with the coal-based energy structure types, which lead to the regional air pollution in Linyi. Air pollution and meteorological conditions have a direct relationship. In this paper, four meteorological factors such as temperature, relative humidity, wind direction and wind speed are taken as an example to introduce the change characteristics from 2014 to 2015, the basic meteorological conditions and the correlation between six basic pollutants and meteorological factors were analyzed in Linyi. The backward trajectory of the typical haze pollution in the winter of Linyi was analyzed.更多还原
