摘要
通过对１９９７年初冬给社会造成严重危害的一次大雾的机理分析，我们认为当水汽与天气形势条件具备时，在河南省单纯的辐射作用是可以形成持续性大雾天气的，而逆温层的不断重建是大雾得以维持的关键所在。近地面层充沛的水汽是大雾形成和维持的必要条件之一。
The mechanism of a heavy fog which result serious problems in winter 1997 Henan province was analysed.It concludes that if the water vapor condition and weather tendency condition are satisfied,continuous heavy fog could be formed by radiation effect.The continuous reconstruction of the conversion and the sufficient water vapor from LBL are necessary for the heavy fog's formation and maintenance.
