摘要
根据云岭白马雪山３ａ多的垂直气候观测资料分析，气温垂直递减率比一般地区大，西坡为０７１℃／１００ｍ，东坡达０７８℃／１００ｍ；在一定海拔高度范围内，降水量随高度升高而增加，在“三江”最狭窄的平行岭谷地段，最大降水高度出现在背风坡（东坡）上部海拔３７００－３８００ｍ之间；风对降水量的影响显著，风口处的降水量比非风口处的观测场内少８％－１２％。
According to measuring data of vertical climate in Yunling Baima Snow mountains for more than three months,the vertical lapse rate of air temperature is 0.71℃/100m on the western slope and 0.78℃/100m on the eastern site.Within definite limits of altitude,the precipitation increases with the rise of altitude.In the narrowest part of the parallel mountain valleys of the “Three River”(Nujiang,Lancangjiang and Jinshajiang) area,the maximum precipitation height is at 3 700 - 3 800 m above sea level on the leeside(eastern slope).Wind has obvious impact on the precipitaton which,at the windgap is 8%-12% less than that in area around meteorological observing station locating on the nonwind gap.
