摘    要:1991年7月在HEIFE实验区沙漠站进行了一次水汽输送观测实验。观测发现近地面层内比湿廓线常常出现极小值,该极小值高度为零水汽通量面的高度。这个高度以上水汽向下输送,廓线呈逆湿特征,这个高度以下水汽向上输送,廓线呈蒸发特征。沙漠上空近地面层内水汽不是常通量,在一个固定高度上观测到的水汽通量和“潜热通量”不能代表地面的蒸发量和潜热通量。

关 键 词:水汽输送  近地面层  水汽通量  廓线  观测  沙漠  逆湿  高度  绿洲  潜热通量

Abstract:An observation experiment about water vapour transportation over desert is carried out at desert station in the HEIFE on July 1991 to find the specific humidity profiles often appear minimum in the surface layer. The level of the minimun value is at the height of zero water vapour flux. The water vapour is transported downwards and the profile of specific humidity appears inverse humidity character above the zero flux height, but the vapour is transported upwards and the profile is evaporation character under the zero flux height. The water vapour flux is unconstant in the surface laved at a fixed level, can not represent the evaporativity and the latent heat flux on ground surface.
Keywords:Desert  Surface layer  Water vapour transportation
