摘要
利用1990-2012年南昌市大气能见度资料和地面气象要素的观测资料,对大气能见度变化规律统计找出其与气象要素关系,利用2006-2012年空气污染物监测数据,分析了南昌市大气能见度变化规律和空气主要污染物的关系。结果表明:南昌大气能见度有较明显的年际变化、月季变化和日变化特征;能见度与相对湿度呈显著负相关;与空气污染物SO2、NOx质量浓度呈弱负相关。
this paper studied the performance of atmospheric visibility at Nanchang. The relationship between atmospheric visibility and the meteorological elements was analyzed by using the statistical method based on the data of Nanchang atmospheric visibility and the observed record of ground meteorological elements from 1990 to 2012. The relationship between the major air pollutants and the atmospheric visibility also was studied according to the air pollutant monitoring data from 2006 to 2012. The result shows that Nanchang atmospheric visibility has the characteristics of obvious interannual variability, monthly and diurnal variation; the visibility was significantly and negatively correlated to relative humidity; there was weakly negative correlation between the air pollutants SO2, NOx concentration and the visibility.
