Most climate models suggest amplification of global warming in high mountains, but observations are less clear. Using comprehensive, homogeneity‐adjusted temperature records from over 1000 elevation stations across the globe, we examine causes changing trends with elevation, assessing roles free atmospheric change, topography (exposure and aspect), cryospheric feedback. The data show that observed 20th century most rapid near annual 0°C isotherm due to snow‐ice Mountain summit freely...
Abstract Quantifying rates of climate change in mountain regions is considerable interest, not least because mountains are viewed as “hotspots” where can anticipate or amplify what occurring elsewhere. Accelerating has extensive environmental impacts, including depletion snow/ice reserves, critical for the world's water supply. Whilst concept elevation‐dependent warming (EDW), whereby stratified by elevation, widely accepted, no consistent EDW profile at global scale been identified. Past...
Surface and free‐air temperature observations from the period 1948–2002 are compared for 1084 surface locations at high elevations (>500 m) on all continents. Mean monthly temperatures obtained two homogeneity adjusted data sets: Global Historical Climate Network (GHCN) Climatic Research Unit (CRU). Free‐air interpolated both vertically horizontally National Centers Environmental Prediction/National Center Atmospheric Reanalysis R1 2.5° grids given pressure levels. The compatibility of is...
Abstract Snowfall is a critical part of the hydrological system in high‐altitude regions and strongly impacted by climate change. This study uses threshold temperature method to estimate spatial temporal variations snowfall at 71 stations across Tibetan Plateau from 1960 2014. Regional air precipitation have increased 0.039°C/yr, 1.43 mm/yr, respectively. While warming rates been fairly uniform plateau, trends are large, with decreases eastern northeastern areas but increases higher...
In complex terrain, air in contact with the ground becomes cooled from radiative energy loss on a calm clear night and, being denser than free atmosphere at same elevation, sinks to valley bottoms. Cold‐air pooling (CAP) occurs where this collects landscape. This article focuses identifying locations landscape subject considerably lower minimum temperatures regional average during conditions of skies and weak synoptic‐scale winds, providing simple automated method map cold is likely pool....
Abstract A high elevation data set of surface temperatures from the Front Range Rocky Mountains in Colorado, USA, is analysed for evidence long‐term change (1952–98). Sites range plains Colorado (1509 m) to alpine tundra (3749 m). Systematic changes surface‐based lapse rates are uncovered, with absolute cooling at highest elevations, but little temperature on plains. There lapse‐rate steepening higher elevations (>3000 synoptic analysis using gridded pressure shows rate be largely...
High elevations are thought to be warming more rapidly than lower elevations, but there is a lack of air temperature observations in high mountains. This study compares instantaneous values land surface (10:30/22:30 and 01:30/13:30 local solar time) as measured by Moderate Resolution Imaging Spectroradiometer MOD11A2/MYD11A2 at 1 km resolution from the Terra Aqua platforms, respectively, with equivalent screen-level temperatures (in same pixel). We use transect 22 situ weather stations...

Abstract Systematic analyses of the daytime and nocturnal precipitation changes provide a better understand impact global warming on environment. In this study, across China from 1990 to 2019 was analyzed using observational data 698 meteorological stations. Both have increased in western parts (including Continental basin, headwaters Yangtze River Yellow basin), whereas trends eastern part are more complex. Climatological differences between summer were significant than other seasons. We...
ABSTRACT In Ireland, the Nahanagan Stadial (NS) was characterised by cirque glacier, plateau icefield and mountain ice cap expansion is named after glacier type‐site of Lough in Wicklow Mountains. This period broadly equivalent to Younger Dryas Greenland Stadial‐1 (GS‐1: ~12.9–11.7 ka). Here, we provide first evaluation full extent NS glaciation Mountains combining solar radiation modelling, mapping glacial geomorphology, 10 Be 26 Al cosmogenic surface exposure dating, 3D reconstructions...
Hourly temperature and humidity observations were obtained over 16 months from loggers ranging in elevation 1890 to 5800 m a.s.l. up the southwestern slope of Kilimanjaro, Tanzania. The vertical gradient mean air is non-linear, with treeline weakening snow-ice line enhancing it. On average, moisture availability (both relative absolute vapor pressure) decreases elevation, but seasonal diurnal variability (RH) enhanced toward mountain summit. strong cycle shown be an outcome upslope transport...
The heights of the atmospheric freezing level have increased over most glacierized areas High Asia during 1971–2010, especially in Altai Mountains, eastern Tianshan and northeastern margins Tibetan Plateau. systematic increase (FLHs) is evidenced from both radiosonde National Centers for Environmental Prediction/National Center Atmospheric Research reanalysis data. Eleven glaciers with long-term observations are selected typical high-elevation mountain ranges to examine relationship between...
ABSTRACT The C erdanya valley in northeast S pain experiences intense cold air pooling which decouples the atmosphere from regional circulation, especially winter. This makes temperature prediction a challenge. A network of 40 sensors was installed 2012 along seven elevational transects to collect hourly temperatures throughout pool, enabling measurement detailed pool structure for first time. Sensors were also upper onflent comparison, where previous research has shown that there is reduced...
Abstract Subarctic Scandinavia is expected to experience significant temperature increases over the next century. How this increase will influence local scale climate largely unknown. This study examines variability in subarctic where unusual solar geometry means that classic diurnal cycle of mid‐latitudes has limited application. Near surface air data were collected from a high density network 60 loggers covering approximately 20 km 2 valley system around Kevo Research Station (69°45′N,...
Recent high-resolution meteorological data from the Pennines of northern England are used to study temporal variation in surface temperature lapse rates. A regression approach uncovers significant relationships between rates and solar input, mean temperature, vertical mixing (modeled through wind speed), atmospheric moisture (specific relative humidity). Prediction is successful, especially during spring, summer, autumn, with r2 above 0.66 (66%). Lapse shallower for higher temperatures a...
The recession of the current ice fields near summit Kilimanjaro has been shown to be controlled largely by climate. Despite detailed research into climate, including mass and energy balance modelling, understanding as a whole limited lack observations on mountain slopes. Analysis hourly air temperatures, relative humidities vapour pressures from 22 weather stations installed between September 2012 2015 across south-west north-east are presented for first time. Moisture is move upslope both...
