Abstract The northwestern corner of China (NWCC) experienced a decadal transition in summer precipitation during 1982–2010, with significant upward trend 1982–2000 (P1) but downward one 2001–2010 (P2). A spatially unbounded dynamic recycling model is developed to estimate the moisture sources and transport variations based on ERA‐Interim data. results suggest that more than 88% NWCC has external origins southwest northwest terrestrial areas. increasing P1 can be explained by contribution...

Northwest China is a typical arid and semi-arid region an important climate-sensitive vulnerable area. In recent decades, this has experienced notable trend toward humidification. Understanding the characteristics trends of precipitation atmospheric water vapor cycle in area essential for predicting future evolution phenomenon. Using observational reanalysis data, study classified from 1961 to 2020 into 20 levels, ranging light heavy events. The analysis shows that overall increase largely...

Water vapor is critical to Arctic sea ice loss and surface air warming, particularly in winter. Whether the local process or poleward transport from lower latitudes can explain warming still a controversial issue. In this work, hydrological tool, dynamical recycling model (DRM) based on time-backward Lagrangian moisture tracking, applied quantitatively evaluate relative contributions of evaporation external sources Barents–Kara Seas (BKS) winter during 1979–2015. On average, moistures 35.4%...

Dynamic recycling model (DRM) and reanalysis data were used to study the interaction between land surface atmosphere during warm season from 1979 2010 across arid semi-arid regions of China. The nonlinear trends common key land–atmosphere variables extracted. For whole region, precipitation ratio showed an increasing trend, especially in period before 1990s. Simultaneously, also found regionally related precipitation, such as soil moisture, evaporation, efficiency, low-level cloud...

The description, experiment design and outputs presented. Three members’ experiments conducted CAMS-CSM, with two members starting from different initial conditions, one excluding stratospheric aerosol identify effect volcanic eruptions. also validated using...

Abstract The datasets for the tier-1 Scenario Model Intercomparison Project (ScenarioMIP) experiments from Chinese Academy of Sciences (CAS) Flexible Global Ocean-Atmosphere-Land System model, finite-volume version 3 (CAS FGOALS-f3-L) are described in this study. ScenarioMIP is one core MIP phase 6 Coupled (CMIP6). Considering future CO 2 , CH 4 N O and other gases’ concentrations, as well land use, design involves eight pathways, including two tiers (tier-1 tier-2) priority. Tier-1 includes...

Model simulations show that drought may become more severe and widespread in the 21st century due to human-induced global warming. However, contributions from key factors model-projected changes China have not yet been examined detail. We used self-calibrated Palmer Drought Severity Index with Penman–Monteith potential evapotranspiration (scPDSIpm) based on 10 model selected Coupled Intercomparison Project Phase 6 (CMIP6). investigated precipitation (P), near-surface air temperature specific...

In this study, the performance of CMIP5 models in simulating El Niño-Southern Oscillation (ENSO) is evaluated by using a new metric based on percolation theory. The surface air temperatures (SATs) over tropical Pacific Ocean are constructed as SAT network, and nodes within network linked if they highly connected (e.g., high correlations). It has been confirmed from reanalysis datasets that undergoes an abrupt phase transition when influences sea temperature anomalies (SSTAs) below strong...

The western Pacific subtropical anticyclone ( WPSA ), which bridges the El Niño events and East Asian summer monsoon, is generally enhanced in boreal after events. However, it becomes weaker late (July–August) of 2016, following 2015/2016 super event, indicating failure previous experience. Our results suggest that 2016 associated with extinction Indian Ocean capacitor effect, presenting cold sea surface temperature anomalies SSTAs ) tropical WTIO fast decaying spring. Compared case...

For the area of Eurasia concentrated with developing countries (referred to here by abbreviation DPEA), mainly located in Asia and Eastern Europe, this work presents datasets gridded meteorological drought events country-based risk combining multiple indices socio-economic data. A basic dataset during 1950–2015 is extracted from three indices: self-calibrating Palmer Drought Severity Index, Standardized Precipitation Evapotranspiration Index.
