利用在扎当冰川山口（北纬30°28.07′n,90°39.03′e, a.s.l. 5 800 m）设置的3个自动气象站（AWS） 1年的观测资料，讨论了年青entanglha山南坡（北坡30°22.87′n,90°40.36′e, a.s.l. 5 100 m）和北坡（北坡30°29.06′n,90°37.46′e, a.s.l. 5 400 m）南坡和北坡的差异。扎当冰川冰口、南坡和北坡年气温分别为-6.9℃、-1.1℃和3.4℃。在消融期间，北坡（扎当冰川）的递减率较高，年递减率为0.87℃/100 m。月气温变化幅度和年递减率在高海拔地区波动较大；海拔高度与相对湿度呈正相关，与饱和水压呈负相关，饱和水压最大值出现在7月份；在这个范围内，大气和局地环流也很明显。月总辐射最高发生在5月，由于大气、云中水汽和地表热条件的差异，南坡辐射低于北坡。
Using one year observational data from three automatic weather stations(AWS) set up in the col of the Zhadang Glacier(30°28.07′N,90°39.03′E,5 800 m a.s.l.),the southern slope(30°22.87′N,90°40.36′E,5 100 m a.s.l.),and the northern slope(30°29.06′N,90°37.46′E,5 400 m a.s.l.) of Mt.Nyainqentanglha in the Tibetan Plateau,the seasonal climatic features have been analyzed,including air temperature,humidity,wind direction and wind speed,saturated water pressure and radiation.The differences between the southern and northern slope of Mt.Nyainqentanglha have been discussed.The annual air temperature at the col of Zhadang Glacier,the southern slope and the northern slope is-6.9℃,-1.1℃,and-3.4℃,respectively.During the ablation period,the lapse rate of the northern slope(Zhadang Glacier) is higher,and the annual value is 0.87℃/100 m.The monthly air temperature range and annual lapse rate fluctuate dramatically in the higher altitude;The altitude has a positive relationship with the relative humidity and a negative relationship with the saturated water pressure in the range,and the maximum saturated water pressure occurs in July;The atmospheric and local circulations are also apparent in the range.The highest monthly total radiation happens in May,and the radiation in the southern slope is lower than the northern slope due to difference of the water vapor in atmosphere,cloud and the surface thermal condition between two slopes.
