Abstract: According to the daily precipitation data from Nielamu and Dingri meteorological stations in the Mount Qomolangma region during 1971~2020, the variability of extreme precipitation indexes is analyzed by using different statistical methods. The R10 is the biggest among the R10, R20 and R25, which means the heavy precipitation is the main weather characteristic. The CDD is far greater than CWD, which is more significant in the north slope of the Mount Qomolangma.Most of the extreme precipitation indexes in the south slope are greater than those of in the north slope in the Mount Qomolangma.There is not significant decreasing trend for all the extreme precipitation indexes in the periods of 1971~2020, and the abrupt occurs mainly in 1980s and 1990s. The periodic changes for the extreme precipitation indexes are very different, but the better the correlation between extreme precipitation indexes has, the closer the period would be. In all the extreme precipitation indexes, the PRCPTOT has high correlation with the other extreme precipitation indexes. The results of this research would be helpful for the understanding of the extreme precipitation characteristics in the Mount Qomolangma region, and it also could provide a reference for the Second Tibetan Plateau Scientific Expedition and Research.
