Abstract Forests overlap with large parts of the northern hemisphere permafrost area, and representing canopy processes is therefore crucial for simulating thermal hydrological conditions in these regions. impact through modulation radiative fluxes exchange turbulent fluxes, precipitation interception regulation transpiration. also feature distinct soil layers litter organic matter, which play central roles infiltration evaporation water, while providing insulation deeper ground layers. In...
In the Central Mongolian mountains, presence of permafrost is intimately linked to local topography and ecosystem setting. Permafrost in these areas generally found on north-facing slopes, it an important element hydrological regime, contributing water availability downstream function. Currently, systems are under increased pressure from both intensified land use climate warming. This includes disturbances herd animals, who modify surface energy balance at grassland sites by changing...
Mongolia is one of the most sensitive regions to climate change, located in transition several natural and permafrost zones. Long-term trends air freezing thawing indices can therefore enhance our understanding change. This study focuses on changes spatiotemporal patterns over from 1960 2020, using observations at 30 meteorological stations. Our results shows that index ranges −945.5 −4,793.6°C day, while 1,164.4 4,021.3°C day Mongolia, their spatial clearly link latitude altitude. During...
Abstract This study presents the results of permafrost mapping in Mongolia based on TTOP (temperature‐on‐top‐of‐permafrost) approach, which were validated against situ measurements at various locations. In indicated that mean annual ground temperature (MAGT) ranged from 0.6 to 2.2°C interannually, showing greatest variability when furthest 0°C. The differences between modeled and measured MAGTs exceeded ±1°C locations where was a nonequilibrium state controlled predominantly by local...
Abstract. Grazing by livestock can alter the surface conditions at grassland sites, impacting transfer of energy between atmosphere and ground consequentially temperatures. In this study, we investigate cover in summer winter measure temperatures over 14 months sites Central Mongolia that feature different grazing intensities (intensely ungrazed) topographic aspects (north- south-facing). Overall, intense leads to a substantially reduced vegetation cover, altered snow lack litter...
In Central Asia, the ground thermal regime is strongly affected by interplay between topographic factors and ecosystem properties. this study, we investigate governing of in an area Mongolia, which features discontinuous permafrost characterized grassland forest ecosystems. Miniature temperature dataloggers were used to measure near-surface temperatures at c. 100 locations throughout 6 km 2 large study area, with goal obtain a sample sites that can represent variability different Mean annual...

Mongolia, a country located in Central Asia, is known for its extreme climate and distinct natural landscape. However, recent years, the effects of global warming have accelerated permafrost degradation, leading to significant ecological environmental disturbances. This study was conducted investigate these changes contribute preservation Mongolia's pristine nature unique structure. Specifically, research focuses on relationship between thawing temperature eastern shore Lake Khuvsgul,...
It is crucial to keep the eastern shore of Khuvsgul Lake, which differentiated from other parts by its unique characteristics. For this case, it necessary study permafrost, plays a certain role in component uniqueness, region. Numerous studies have proven that current climate change has caused accelerating permafrost loss. Therefore, we initiated understand condition on Lake. The preliminary findings were presented. Nine locations, same line but had various natural characteristics, selected...
In this study, we identified the relationship between Ground Surface Temperature (GST) with geography and environmental factors in Terkh River Valley, Mongolia, explored possibility of using satellite data to determine active layer thickness seasonally frozen ground changes. We obtained from three boreholes for permafrost monitoring, ten GST measuring instruments that installed valley. According results, at varied 2.8 6.22 m. Ar borehole, increased by 5 cm per year, while depth Uvur borehole...
The distribution of permafrost in Mongolia is sporadic and discontinuous depending on the location, landscape, temperature. Also, characteristics patterns its soil cover vary across regions. In this study, we aimed to determine distributed regions differences Mongolia. We divided studied into Mongolian-Altai, Gobi-Altai, Khangai, Khuvsgul, collected 164 samples at fixed depths 0-5 cm, 5-15 15-30 30-60 cm 41 profiles around monitoring boreholes. As result, Kastanozems Chernozems soils were...
