利用1959-2014年南昌市地面气象观测资料，分析了56年来南昌霾天的地面温度、湿度、风、气压特征。南昌市霾天多发于地面风速为1~2 m/s、风向为东北风、地面处于1010~1030 hPa高压控制、相对湿度较低的气象条件下。近56年南昌市降水日数的减少、平均风速的降低和相对湿度的变小，也可能促进了霾日数的增加。文章还结合南昌市霾日气象特征探讨治理霾污染的政策，并从气象部门角度提出了霾污染治理的相关建议，可为政府科学开展大气环境管理提供决策参考。%Some characteristics of temperature, humidity, wind, pressure of haze days in Nanchang city are analyzed using ground meteorological observation data from the year 1959 to 2014 . The hazes usually happened on the weather condition of:1~2 m/s wind speed,northeast wind direction,1 010~1 030 hPa atmospheric pressure, lower humidity. The situation happened in nearly 56 years in Nanchang City that precipitation days reduced,the average wind speed reduced and the relative hu-midity became smaller may also promote the haze days. Some policies for haze control are put forward considering characteristics of haze weather, and some suggestions for haze governance are also put forward from the view of meteorological department. These suggestions can provide scientific refer-ence of decision-making for government in atmospheric environmental management.
