摘要
本文分析了重庆1989年12月30日雾的声雷达回波特征与浓雾天气的关系,讨论了雾日大气SO2地面浓度状况.结果表明,声雷达回波与雾的演变有较好的对应;地面污染物浓度与声雷达回波所反应的大气层结状况关系密切,300~400米高度上的逆温层维持较长时间是加重当日大气SO2地面浓度的重要原因。
This paper describes and discusses acoustic sounder echo patterns.Typical of those obtained in Chongqing instances of radiation fog on December30,1989 ,and instances of SO2 concentration. The height of a strong eleveted layer echo is shown to be closely correlated with the fog depth. The results demonstrate a clear correlation the SO2 concentration near the ground and the continuing eleveted inversion layer at 300~400m to the surface.
