Abstract Permafrost in Central Asian is present the Qinghai–Tibet Plateau China, Tien Shan Mountain regions Kazakhstan and Kyrgyzstan, Pamirs Tajikistan, Mongolia. Monitoring of ground thermal regime these over past several decades has shown that permafrost been undergoing significant changes caused by climate warming increasing human activities. During International Polar Year, measured mean annual temperature (MAGT) at a depth 6 m ranged from −3.2°C to 0.2°C on active‐layer thickness (ALT)...
Predicting the future of any given species represents an unprecedented challenge in light many environmental and biological factors that affect organismal performance also interact with drivers global change. In a three‐year experiment set Mongolian steppe, we examined response common grass Festuca lenensis to manipulated temperature water while controlling for topographic variation, plant–plant interactions, ecotypic differentiation. Plant survival growth responses warmer, drier climate...
Agriculture in the boreal and Arctic regions is perceived as marginal, low intensity inadequate to satisfy needs of local communities, but another perspective that northern agriculture has untapped potential increase supply food even contribute global system. Policies across jurisdictions target expansion intensification agriculture, contextualized for diverse social settings market foci north. However, rapid pace climate change means traditional methods adapting cropping systems developing...
The Hovsgol mountain region (49°–52°N, 98°–102°E) of northern Mongolia contains widespread permafrost and comprises the southern fringe Siberian continuous zone. In this paper, we report our initial monitoring by means measuring ground temperatures active layer thickness in boreholes some cryogenic processes under influence climate warming human activities region. average rate increase mean annual is from 0.2°C to 0.4°C per decade. Permafrost has been degrading more intensively during last...
Lake Hövsgöl is located on the southern fringe of continuous permafrost zone in northern Mongolia. This paper describes a GIS-based empirical model that calibrated with ground temperature observations, and utilises multi-criteria approach to derive zones favourability based terrain parameters land cover information. The scores are derived either by logistic regression or from satellite image validated DC resistivity tomography measurements. overall distribution study area well-described...
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...
Abstract Near‐surface temperature variations in different topographic settings were obtained from miniature data‐loggers at 17 locations over a 2‐year period the Lake Hövsgöl area northern Mongolia. These measurements used to analyse influence of vegetation, solar radiation, surface wetness and snow cover on ground thermal regime. An empirical modelling approach was applied order estimate spatial distribution temperatures, presence permafrost depth active layer. Our study shows that...
ABSTRACT The first record of stable isotopes through a complete sequence ice within an open‐system pingo in northwestern Mongolia indicates complex history formation and growth. A continuous section 32 m long was cored the centre Mongot Pingo, cores were analysed for chemical composition. Two different isotope patterns separate sections are identified: 1 freezing 2 semi‐closed system (or closed system) freezing. Discharge measurements observed 2009 after drilling to artesian sub‐pingo water...
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...

This paper describes frost heaving in the Selenge River Basin central Mongolia. Spatial information has been compiled according to predominant composition of ground, soil moisture content and water level, permafrost distribution temperature, depth seasonal freezing/thawing ground. allows creation a permafrost-engineering geology map predict occurrence intensity heave.
