中文摘要：
利用塔中气象站地面辐射等气象资料结合PNIO（空气动力学当量≤10um的悬浮颗粒）质量浓度资料，以2007年4月15日晴天辐射特征为背景对4月22日塔克拉玛干沙漠腹地发生的沙尘暴天气进行局地辐射特征和沙尘气溶胶与净辐射作相关分析。结果表明白天沙尘的辐射强迫对地表有冷却作用，夜间起保温作用。观测期间，总辐射日峰值减少量为507W／m^2，地面长波日峰值增加量为185w／m^2，地面净辐射能量收支表现为白天的日峰值减少量为198w／m^2，夜间的日峰值增加量为40W／m^2。
英文摘要：
Based on the meteorological data and PM10 data from the weather station in the centre of the Takla Makan desert, the local radiation characteristics over there on April 22, 2007, on which the sandstorm weather event occurred, and the correlation of dust aerosol and the net radiation were analyzed and compared with the sunshine day＇ s radiation characteristics on April 15. The results indicate that the radiation forcing of dust aerosol caused surface temperature decreasing in daytime and increasing at night. During the observation period, the peak value of the total radiation decreased by 507 W/m^2, and the peak value of long - wave radiation increased by 185 W/m^2. The maximum of the net radiation decreased by 198 W/m^2 in day time and increased by 40 W/m^2 at night.
