Extreme precipitation occurring on consecutive days may substantially increase the risk of related impacts, but changes in such events have not been studied at a global scale. Here we use a unique global dataset based on in situ observations and multimodel historical and future simulations to analyze the changes in the frequency of extreme precipit...
Extreme precipitation occurring on consecutive days may substantially increase the risk of related impacts, but changes in such events have not been studied at a global scale. Here we use a unique global dataset based on in situ observations and multi-model historical and future simulations to analyse the changes in the frequency of extreme precipi...
In this study, we investigated the spatiotemporal variations of border-crossing dust events (DEs), including floating, blowing dust, and dust storms between Mongolia (MG) and Inner Mongolia (IM), China using the ground-based observations from 91 synoptic stations across the Mongolian Plateau during 1977-2018. We defined the intensity of DEs (progre...
Aeolian processes in temperate grasslands (TGs) are unique because the plant growth–decay cycle, soil water, and land-use interactions affect the seasonal and inter-annual changes in dust events. Land-use types in Inner Mongolian TGs are unique (settled grazing and grass mowing) compared with those in Mongolian TGs. Since 2003, land use has been co...
The threshold wind speed for saltation (Ut), an index of soil susceptibility to wind erosion, is affected by dynamics of various land surface conditions. Little information is available on the primary factors that affect Ut in the Gobi Desert. This study explored seasonal variations of Ut and its relations with land surface conditions at Tsogt-Ovoo...
Wind erosion results in soil redistribution and textural changes on topsoil. There is little information about how these changes affect plant production. Here, we compared simulations of vegetation growth between a wind-eroded scenario and an actual condition at two sites in Mongolian grasslands (steppe and desert steppe) using an ecosystem model....
Tunisia, located on the shores of the Mediterranean, is projected to experience most predominant droughts. However, detailed drought assessments at the regional scale of Tunisia are limited to date, with most studies only focusing on a specific region and/or making use of one drought index. This study identifies both vegetation and agricultural reg...
Climate change is projected to increase the aridity of semi-arid ecosystems, including Mongolian grasslands (MG), which provide ecosystem services that support food supply and pastoralist lifestyle. Here, we conducted a grid-scale (0.5º×0.5º) probabilistic risk assessment of MG under climate change for 40 years (1976–2015) based on probability theo...
Drought is among the highest-impact natural hazards affecting drylands around the world in a warming climate. The Mediterranean region, including Tunisia, is projected to experience the most predominant drying trends worldwide. However, a detailed regional scale study of drought for Tunisia has been limited, hampering an assessment of drought impac...
The article contains an error in its Data section. The author group would like all to note and acknowledge:
While it is known that soil erosion by wind in drylands results in soil loss and redistribution and changes the texture of topsoil, there is little information about how these changes in the topsoil might affect the productivity of vegetation and if they result in degradation of the grasslands in wind-eroded regions such as Mongolian grasslands. In...
Robust changes in climatic hazards, including droughts, heatwaves and dust storms, are evident in many parts of the world and they are expected to increase in magnitude and frequency in the future. At the same time, socio-ecological damage from climate-related disasters has increased worldwide, including the Eurasian steppes, notably Mongolian gras...
In recent years, extreme cold air outbreak events (COEs) in winter have tended to occur more frequently over the mid‐latitudes of Eurasia, including Mongolia, despite marked warming across the continent. In the 2000s, an increase in COEs contributed to huge losses of livestock throughout Mongolia, causing socioeconomic stagnation. This study diagno...
Extreme precipitation often persists for multiple days with variable duration but has usually been examined at fixed duration. Here we show that considering extreme persistent precipitation by complete event with variable duration, rather than a fixed temporal period, is a necessary metric to account for the complexity of changing precipitation. Ob...

The livelihoods of people inhabiting inland Eurasia have long been jeopardized by repeated natural hazards associated with a harsh environment and a cold, arid climate. Dzud is a Mongolian word indicating harsh winter conditions. In the present study, we considered dzud damage (e.g., livestock loss) to result from a combination of climate hazard (e...
Mongolian pastoral husbandry is subject to various climate hazards such as dzud (Mongolian for “severe winter conditions”). Dzud in the 2009/2010 winter affected 80.9% of the country and killed more than 10 million livestock (23.4% of the total). To understand the natural and man-made mechanisms of this dzud, we examined the contributions of dzud-c...

Mongolia is regularly affected by a disaster in which socio-natural factors combine to create peaks of livestock mortality called dzud. The loss of livestock during dzud is the result of a combination of external climatic factors such as hazards, and internal factors such as overgrazing which makes forage resources difficult to access. The increasi...
Socio-ecological damage from climate-related disasters has increased worldwide, including a type of cold-season disaster (dzud) that is unique to the Eurasian steppes, notably Mongolia. During 2000-2014, dzuds killed approximately 30 million livestock and impacted the Mongolian socio-economy. The contributions of both natural and social processes t...
The case study seeks to develop a new dzud risk map for early warning system (EWS) under the Grant-in-Aid for Scientific Research (S) from the Japan Society for the Promotion of Science ‘Integrating Dryland Disaster Science’(4), in collaboration between Nagoya
University (Japan) and the Information and Research Institute of Meteorology,
Hydrology a...
Cross-correlations between inter-annual summer rainfall time series (June to August: JJA) for arid Mongolia and global sea surface temperatures(GSST) were calculated for prediction purposes. Prediction of summer rainfall for four vegetation zones, Desert Steppe(DS), Steppe (ST), Forest Steppe (FS), and High Mountain (HM) using GSSTs for time lags o...
Increases in extreme record-breaking daily precipitation events have accompanied warming temperatures causing increased flooding in many areas of the World, but are not well documented for arid and semi-arid regions. In semi-arid Mongolia where warming has been over 2o C from 1940 to 2008, nomadic herders described their concerns over an increase i...
Aeolian processes in temperate grasslands are unique in that the plant growth-decay cycle, soil moisture/snowpack dynamics, and induced grazing interactively affect seasonal and interannual variations of dust emission. This study uses process-based ecosystem model DAYCENT and unique saltation flux measurements to: (1) identify primary land-surface...
Multi-decadal soil moisture trends and their relationships to precipitation (P) and evapotranspiration (E) were explored in Mongolia. We modified a simple soil-moisture model intended for use in a wide range of practical applications for monitoring of pasture drought across the country, by incorporating soil freezing and snow melt. Daily soil moist...
The present study aims to identify hotspots on the Asian steppe that were vulnerable to widespread drought events in the Northern Hemisphere during 1999–2002, using newly proposed indices of vegetation response (sensitivity and resilience) to drought. Drought sensitivity is defined as vegetation response to decreased precipitation from pre-drought...
Drought frequency, duration, and severity and its impact on pasture productivity in the four main vegetation zones of Mongolia were analyzed using meteorological, soil moisture, and vegetation data during the growing season (April–August) of 1965–2010. Meteorological and pasture drought characteristics were explored using the Standardized Precipita...
We evaluated the performance of the DAYCENT grassland ecosystem model to provide estimations of soil moisture and grass productivity in a temperate grassland ecosystem of Mongolia. The model was parameterized with field experimental data collected at the Bayan Unjuul (BU) site during 2010−2011 consisting of climate, soil physical/chemical propertie...
Severe dust events have increased in the arid and semiarid regions of Mongolia and China during the last decade. It poses a serious threat not only to the grassland livestock and human lives in the source regions but also in downwind regions. An early warning system needed to prevent this serious damage. However, it is difficult to predict dust eve...
Continental climate is established as a result of a complex interplay between the atmosphere and various
land-surface systems such as the biosphere, soil, hydrosphere, and cryosphere. These systems function as climate
memory, allowing the maintenance of interannual atmospheric anomalies. In this paper, we present
new observational evidence of an in...
Mongolia has an arid and cold climate due to its geographical settings of inland and mid-latitude highlands. The soil moisture varies seasonally, depending mainly on the balance of precipitation and evapotranspiration as well as on winter soil-freezing and spring snowmelt. Soil moisture climatology (1986-2005) for Mongolia is presented with a focus...
We propose an index of soil and land surface conditions for
wind erosion to investigate their effects on dust outbreaks. The
index is the normalized dust outbreak frequency (NfDO), which
is the ratio of dust outbreak frequency to strong wind frequency.
NfDO for April was always low in Mandalgobi, Mongolia, when the
accumulated precipitation amount...
Drought has become widespread throughout the Northern
Hemisphere since the mid-1950s, affecting the Mongolian steppe
and pastureland used for livestock. Given this background, we investigated
the relationship between modeled root-zone soil moisture
(Wm) and vegetation activity based on Normalized Difference
Vegetation Index (NDVI) data for the Mong...
A long-term (1963–2002) set of daily maximum and minimum temperature and precipitation data are analyzed for the Hövsgöl Basin area, Mongolia. Six indices of extreme temperature and eight indices of extreme precipitation are examined. Results suggest that climate conditions over northern Mongolia are changing as indicated by a warming trend identif...

Near-surface temperature variations in different topographic settings were obtained from miniature temperature data-loggers at 17 locations over a 2-year period in the Lake Hövsgöl area in northern Mongolia. These measurements were used to analyse the influence of vegetation, solar radiation, surface wetness and snow cover on the ground thermal reg...
Northern Mongolia represents the southern-most extension of continuous
permafrost and the border of the Siberian taiga forest in Asia. The
mountainous watershed valleys of Lake Hövsgöl are in a
forest/steppe transition zone characterized by continuous permafrost in
the upper valleys and ridge tops and discontinuous permafrost in lower
valley areas....

The project will assess climate risk for the herder communities’ well-being and the rangelands they depend on, across Eurasian drylands, for the present (1981−2020) and future (2020−2050) periods. We will quantify the risk and vulnerability of the rangelands to climate change and regional land use by identifying vulnerable hotspots, climate change impacts on herders’ welfare by combining with region-specific socio-economic changes, and identifying the most effective adaptation strategies to current and future climate change. The main target area is three pastoral regions in western (Turkey), central (Kazakhstan), and
eastern (Mongolia).
This project attempts to create a big hub on researchgate.net networking the Mongolian scientists and seeking any research collaborations among them. Particularly, the collaborators will update timely the current list of new publications co-authored by the Mongolian scientists who are from both foreign universities and also the local research institutions.
In recent decades, weather/climate-related disaster losses have increased in Mongolia due to adverse impacts of climate change that combined with increasing vulnerabilities of the grassland ecosystem/people (e.g., herding communities) to hazards. Therefore, it is crucial to strengthen the disaster risk reduction system in Mongolia that depends on a rigorous understanding of the dimensions of causal factors of hazards and vulnerability, as well as proper assessment of changes in those dimensions.
