摘要
利用空气质量监测和气象资料,分析得到2014年8月河北全省各市平均AQI(空气质量指数)普遍在200以下;温度、相对湿度、平均风速和降水对局地污染物浓度增加有一定贡献;在无显著降水期间,混合层高度的高/低对应着AQI值的低/高;与2013年同期相比,全省空气污染物浓度有所下降。
Based on the air quality observing data and meteorological data, the article finds out that the AQI of cities in Hebei province were all below 200 in August, 2014. During this period, the temperature, relative humidity, wind speed and precipitation made considerable contribution; during the periods which had no significant precipitations, the mixed layer height always had an opposite trend to that of AQI value. Comparing with the August in2013, the pollutant concentration in Hebei province decreased.
