【摘要】 利用北京地区地面自动化观测资料中的能见度、相对湿度及人工业务观测记录数据,结合卫星观测的雾厚度数据图,对2011年10月底至12月初的3次大雾天气过程进行了实时动态监测和数据分析,初步形成地面自动化观测资料在雾的监测过程中的应用产品,研究表明,利用能见度数据以及相对湿度数据可以完整地监测大雾的发生、发展、持续和消散过程,与气象业务上应用的卫星观测到的雾生消趋势基本一致,但是在生消时间的监测上更具优势。更多还原

【Abstract】 Three fog events in Beijing were dynamically monitored in real time from the end of October to early December in 2011 using the visibility and relative humidity data from surface AWS(Automated Weather Station)and artificial observation,comparing with fog thickness data detected by satellites.The results show that the processes of fog occurrence,development,and dissipation can be monitored by means of the visibility and relative humidity observation.Comparing with the analysis of satellite data,the visibility and relative humidity data have the same trend and advantages in detecting the life cycle of a fog event.更多还原
