区域重度雾霾污染特征及其与气象因子的相关性研究

Characteristics of Regional Heavy Haze Pollution and Its Correlation with Meteorological Factors

为研究某重度雾霾污染区域的雾霾污染特征及其与三种气象因子的相关性,文章选取一个重度雾霾污染区域,采集监测站数据作为研究中的气象数据,研究该区域重度雾霾污染的长时段特征、年均变化趋势与分布特征;分析不同季节中重度雾霾污染特征与湿度及温度的相关性;绘制风向的污染极坐标图,分析重度雾霾污染特征与风向的相关性。结果表明,污染物与相对湿度呈正相关关系,与温度呈现不确定的相关性关系,与风向呈现正相关关系。

In order to study the characteristics of haze pollution in a heavy haze pollution area and its correlation with three meteorological factors,this paper selected a heavy haze pollution area and collected monitoring station data as the meteorological data.It studied the long-term characteristics,annual variation trend and distribution characteristics of heavy fog pollution in the area.The seasonal concentration change trend and monthly change rule of pollutants are studied to calculate the correlation coefficient between various air pollutants and relative humidity and temperature in four seasons.It analyzes the correlation between moderate and severe haze pollution characteristics and humidity and temperature in different seasons,drew pollution polar coordinates of wind direction,and analyzes the correlation between heavy haze pollution characteristics and wind direction.The result showed that the pollutants have a positive correlation with relative humidity,an uncertain correlation with temperature,and a positive correlation with wind direction.
