“…Sutai, Tsambagarav, and Munkhkhairkhan. D. Otgonbayar calculated a total of 24 glaciers covering 48.13 km 2 in 1970, and again in 2008 when 17 glaciers covered 26.57 km 2 [13,15]. Additionally, Kamp and Pan independently estimated 27.4 km 2 glacial area in 2011.…”

“…By the estimation of Otgonbayar. D, 24 glaciers together had an area of 48.13 km 2 in 1970, and in 2008, 17 glaciers covering 26.57 km 2 remained [13,15]. This shows that between 1970 and 2008, seven glaciers completely melted.…”

“…Along a northeast/southwest axis, the range separates a tectonic depression from the mountains of the Mongolian-Altai. Small rivers such as the Doloon Nuur, Shuurkhai, and Bort in the north part, and the Uyench and Bodonch Rivers in the south drain the area [15]. The climate zone includes harsh winters and humid, cold summers.…”

“…These glaciers are located from the Doloonnuur (Nuur means the Lake) at the northwest to Ikh Turgen at the southeast of the mountain; the northwest part is called the massif of Doloonnuur, the central part is called the Shuurkhai Massif, and the southeast part is called Khukhnuurs Massif (Figure 1). Among these, at the Shuurkhai Massif, five glaciers occupy 22.39% of the total area, eight glaciers occupy 40.68% of the area of the Massif of Doloonnuur, and four glaciers occupy 36.92% of the total area of the Khukhnuur Massif [15]. By the estimation of Otgonbayar.…”

Mt. Munkhkhairkhan is the most crucial region for understanding climate and glaciation changes in Mongolia. This study investigated the relationship between glacial area changes and the climate elements of Mt. Munkhkhairkhan in the Mongolian-Altai Mountains using a remote sensing approach, in-situ observations, the Mann–Kendall (MK) test, Innovative Trend Analysis Method (ITAM), Sen’s slope estimator test, and statistical analysis. The study results showed that for the last 30 years, the annual average air temperature of Mt. Munkhkhairkhan has been slightly increasing. Total annual precipitation (mainly snow) in the mountain area decreased from 1990 to 2000, but since 2000, a significant increase in precipitation levels has appeared. For the last 30 years, the glacial area has decreased by 32% to 11.7 km2. Multiple regression results showed a strong correlation between Temperature, Precipitation, and Glaciers (Multiple R = 0.69, R2 = 0.48). Ruther indicated that Temperature (t = −2.332, p = 0.036) and Precipitation (t = −3.212, p = 0.007) were significant predictors in the model. Air temperature and precipitation explained 48 percent of the change in the glacier area, and R = 0.69 is a strong correlation. The glaciers and snow area in the study area have changed due to climate warming and precipitation changes and are located in arid and semi-arid regions of Central Asia. This study of Mt. Munkhairkhan shows that climate change significantly impacts glaciers and snow.
