Temporal-spatial variability of modern climate in the Altai Mountains during 1970-2015

temperature occurred in sub-region 2 at a rate of 0.45˚C/decade. The next was in sub-region 3 at a rate of 0.42˚C/decade and the third in sub-region 1 at 0.38˚C/decade. Being different to the temperature fluctuations, the trends of MAP were insignificantly and their rates were 7.7 mm/decade in sub-region 1, 1.9 mm/decade in sub-region 2 and 8.2 mm/decade in sub-region 3, respectively (Fig 7B). Temperature/precipitation trend-elevation relationship We further analyzed the temperature/precipitation trends in different elevations (i.e., high ele- vation >2000 m, middle elevation at 2000–1000 m and low elevation <1000 m) (Fig 8). The stations in high elevation are Kara-Tyurek and Yalalt. Mugur-Aksy, Kosh-Agach, Olgiy, Khovd and Qinghe are contained in middle elevation and the remaining stations are included in low elevation. A significant warming during 1970–2015 with different rates was found in Fig 7.
