摘要
我们于１９９１年８，１０月，在ＨＥＩＦＥ实验区的三种下垫面（农田绿洲、戈壁、沙漠）上进行了边界层探测。分析结果表明，被大片戈壁或沙漠包围的绿洲在整个时次上２００—３００ｍ以下边界层内温度低于周围环境。湿度大于周围环境。绿洲“冷岛效应”明显，其影响高度可达２００ｍ。
The observations about the structure of planetary boundary layer over three kinds of underlying surface (Oasis,Gobi,Desert) in HEIFE area are carried out on Aug and Oct 1991 The results show,the temperature of the oasis surrounded by wide Gobi and Desert is obviously lower than that of enviroment and humidity of oasis is higher than that of the enviroment in the boundary layer under 200 300 m on whole day The “cold island effect” is so obvious and its affection altitude can get to 200 m The characteristic of diurnal variation of wind is evident in HEIFE area
