中文摘要: 利用中国科学院青藏高原研究所纳木错多圈层综合观测研究站在念青唐古拉峰扎当冰川垭口
（30.47°N、90.65°E，5800m）和纳木错站（30.77°N、90.99°E,4730m）的逐日平
均气温、相对湿度、气压等资料,与同期NCEP/NCAR再分析资料进行了对比分
析,讨论了再分析资料在纳木错流域湖泊/冰川区气候变化研究中的适用性。结果表明：扎当
冰川垭口和纳木错站气压再分析资料的可信度好于气温,相对湿度稍差; 扎当冰川垭口气压
和相对湿度再分析值与实测值的差值在冬季偏大,夏季偏小,气温则相反。在研究期间, 总体
上再分析资料在冰川区的可信度好于湖泊区,再分析资料能很好地反映该地区地面气压、气
温和相对湿度的日变化特征, 在应用到该地区气候变化的研究时应考虑地形的影响。

Abstract:with the reanalysis data f
rom the National Centers of Environmental Prediction/National Centers for Atmosp
heric Research (NCEP/NCAR) during the same period. The reanalysis data can captu
re much of the synoptic scale variability in daily mean pressure, temperature a
n
d relative humidity. Among them, the reanalyzed pressure is more confident than
temperature and relative humidity at the Col of Zhadang Glacier and Nam Co Stati
on. Differences between the reanalyzed and observational daily mean pressure and
relative humidity are large in winter and less in summer, while differences bet
ween the reanalyzed and observational daily mean temperature are opposite. Relia
bility of reanalysis data is better at the Col of Zhadang Glacier than at Nam Co
Station. The reanalyzed data can be used to study the trends of climate change
in the glacier and lake area in the Nam Co Basin, and more attentions should be
given to influences of topography.
