Using annual mean, maximum, minimum air temperature and monthly mean precipitation data from 5 weather stations in Mt. Qomolangma region from 1971 to 2004, climatic linear trend, moving mean, low-pass filter and accumulated variance analysis methods, the spatial and temporal patterns of the climatic change in this region were analyzed. The main findings can be summarized as follows: (1) There is an obvious ascending trend for the interannual variation of air temperature in Mt. Qomolangma region and the ascending trend of the highest station, Tingri, is most significant. The rate of increasing air temperature is 0.0234 oCa-1 in Mt. Qomolangma region and 0.0302 oCa-1 in Tingri. The air temperature increases more strongly in non-growing season. (2) Compared with China and the global mean, the warming of Mt. Qomolangma region occurred early. The linear rates of temperature increase in Mt. Qomolangma region exceed those for China and the global mean in the same period. This is attributed to the sensitivity of mountain regions to climate change. (3) The southern and northern parts of Mt. Qomolangma region are quite different in precipitation changes. Stations in the northern part show increasing trends but are not statistically significant. Nyalam in the southern part shows a decreasing trend and the sudden decrease of precipitation occurred in the early 1990s. (4) Compared with the previous studies, we find that the warming of Mt. Qomolangma high-elevation region is most significant in China in the same period. The highest automatic meteorological comprehensive observation station in the world that was set up at the base camp of Mt. Qomolangma with an elevation of 5032 m above sea level will play an important role in monitoring the global climate change.
