Abstract Drylands are home to more than 38% of the world's population and one most sensitive areas climate change human activities. This review describes recent progress in dryland research. Recent findings indicate that long‐term trend aridity index (AI) is mainly attributable increased greenhouse gas emissions, while anthropogenic aerosols exert small effects but alter its attributions. Atmosphere‐land interactions determine intensity regional response. The largest warming during last 100...
Abstract. This study examined surface air temperature trends over global land from 1901–2009. It is found that the warming trend was particularly enhanced, in boreal cold season (November to March) semi-arid regions (with precipitation of 200–600 mm yr−1) showing a increase 1.53 °C as compared annual mean 1.13 land. In mid-latitude areas Europe, Asia, and North America, temperatures increased by 1.41, 2.42, 1.5 °C, respectively. The contribute 44.46% annual-mean land-surface trend. Northern...
Abstract How long will the four seasons be by 2100? Increasing evidence suggests that length of a single season or in regional scales has changed under global warming, but hemispherical‐scale response past and future remains unknown. We find summer Northern Hemisphere midlatitudes lengthened, whereas winter shortened, owing to shifts their onsets withdrawals, accompanied shorter spring autumn. Such changes lengths can mainly attributed greenhouse‐warming. Even if current warming rate does...
A warming hiatus is a period of relatively little change in global mean surface air temperatures (SAT). Many studies have attributed the current to internal climate variability (ICV). But there less work on discussion dynamics about how these ICV modes influence cooling over land Northern Hemisphere (NH). Here we demonstrate was more significant continental NH. We explored from perspective and investigated mechanisms reversing accelerated hiatus, SAT throughout NH land. It found that Arctic...
Abstract The variability of soil moisture over East Asia was analyzed using a long‐term data set from the Global Land Data Assimilation System. Overall, clear decreasing trend occurred period 63 years, with pronounced drying northeast China, north part Mongolia, and Russia near lake Baikal. Statistical analyses show that precipitation global warming have different effects on decrease in moisture. qualitative analysis quantitative contributions illustrated is driven primarily by enhanced...
Abstract Since the slowing of trend increasing surface air temperature (SAT) in late 1990 s, intense interest and debate have arisen concerning contribution human activities to warming observed previous decades. Although several explanations been proposed for warming-trend slowdown (WTS), none has generally accepted. We investigate WTS using a recently developed methodology that can successfully identify separate dynamically induced radiatively forced SAT changes from raw data. The exhibited...
To quantitatively estimate the divergences in natural and anthropogenic dust emission fluxes among different climatic regions, total emissions at global scale from 2007 to 2010 were simulated this study. Despite widely scattered distribution, area of potential sources was found slightly higher than that sources. The distribution 1.61 × 107 km2 January 1.54 July, respectively. contributed 81.0% 19.0% residual. flux 6.34 ± 0.31 μg m−2 s−1 1.01 0.07 s−1, Especially, situated regions. Natural...
Abstract Rapid warming over the Tibetan Plateau (TP) has been associated with an increasing trend in atmospheric water vapor content, which is critical for recharging Asian tower. However, mechanism wetting phenomenon remains unclear. Long‐term changes moisture balance and precipitation (PRE) recycling processes are investigated using ERA5 reanalysis from 1979 to 2019. The TP mainly due summer significantly increases western TP. Based on analysis, it found that PRE, evaporation, convergence...
Abstract. As climate change has occurred over east Asia since the 1950s, intense interest and debate have arisen concerning contribution of human activities to observed warming in past decades. In this study, we investigate regional surface temperature during boreal cold season using a recently developed methodology that can successfully identify separate dynamically induced (DIT) radiatively forced (RFT) changes raw air (SAT) data. For averages, DIT RFT contribute 44 56 % SAT Asia,...
Abstract The rapid urbanization in China and the long‐range transport dust (LRTD) from arid semi‐arid areas has resulted an increase of PM 10 concentration. In this study, interpretable deep learning model [deep forest (DF)] with FY‐4A top‐of‐the‐atmosphere reflectance (TOAR) data were used to obtain hourly China. optimal average R 2 10‐fold cross validation can achieve 0.85 (13:00 Beijing time); (RMSE, μg/m³) daily, monthly, annual averages 0.82 (24.16), 0.97 (6.53), 0.99 (2.30),...
Abstract. Although anthropogenic dust has received more attention from the climate research community, its dominant role in production process is still not identified. In this study, we analysed relationship between and population density/change over global semi-arid regions found that are major source producing dust. The results showed obvious cropland than other land cover types (crop mosaics, grassland, urbanized regions) of increases as density grows to 90 persons km−2. Four selected...
Due to urbanization and industrialization, PM2.5 (particulate matter with a diameter less than 2.5 μm) pollution has become serious environmental problem. The low spatial resolution insufficient coverage of observation stations affect research on causes human health risks. With the launch FY-4A, new generation Chinese geostationary weather satellites, it is possible obtain high temporal covering all China. In this study, FY-4A top-of-the-atmosphere reflectance data, meteorological factors,...
The global warming slowdown or hiatus, began around the year 2000 and has persisted for nearly 15 years. Most studies have focused on interpretation of hiatus in temperature. In this study, changes a aridity index (AI) were analyzed by using newly developed dynamical adjustment method that can successfully identify separate dynamically induced radiatively forced raw data. AI Palmer Drought Severity Index produced wetting zone over mid-to-high latitudes Northern Hemisphere recent decades....
The source area of the Yellow River Basin (SYRB) is located in northeastern Tibetan Plateau, and precipitation SYRB great importance to water resources throughout whole basin. By analyzing summer SYRB, we found that an 11.4% increase occurred during 2003–2019 compared with 1982–2002. Such interdecadal was due significant changes moisture contribution from external source. In past 38 years, 95.4% vapor for precipitable came local evapotranspiration (10.6%), Plateau (35.8%), central Eurasian...
