Abstract. Using the daily records derived from synoptic weather stations and NCEP/NCAR ERA-Interim reanalysis data, variability of winter haze pollution (indicated by mean visibility number hazy days) in Beijing–Tianjin–Hebei (BTH) region during period 1981 to 2015 its relationship with atmospheric circulations at middle–high latitude were analyzed this study. The BTH had distinct inter-annual inter-decadal variabilities without a significant long-term trend. According spatial distribution...
Abstract Dust aerosols play key roles in affecting regional and global climate through their direct, indirect, semi-direct effects. events have decreased rapidly since the 1980s East Asia, particularly over northern China, primarily because of changes meteorological parameters (e.g. surface wind speed precipitation). In this study, we found that winter (December–January–February) Arctic amplification associated with weakened temperature gradients along zonal winds is responsible for large...
Abstract In addition to weather conditions and pollutant emissions, the degree which topography influences occurrence development of haze pollution in downtown Beijing mechanisms that may be involved remain open questions. A series atmospheric chemistry simulations are executed by using online-coupled Weather Research Forecasting with Chemistry (WRF-Chem) model for November-December 2015 different hypothetical topographic height scenarios. The simulation results show exerts an important...
The emergence of ChatGPT has generated much speculation in the press about its potential to disrupt social and economic systems. Its astonishing language ability aroused strong curiosity among scholars performance different domains. There have been many studies evaluating GPT-4 tasks disciplines. However, a comprehensive review summarizing collective assessment findings is lacking. objective this survey thoroughly analyze prior assessments GPT-4, focusing on reasoning abilities, scientific...
Abstract Dust aerosols are a major type of aerosol over the Tibetan Plateau (TP) and influence climate at local to regional scales through their effects on thermal radiation snow‐albedo feedback. Based Modern‐Era Retrospective Analysis for Research Applications, Version 2 (MERRA‐2) data set, we report an increase 34% in atmospheric dust high troposphere TP during spring season 2000s comparison 1990s. This result is supported by 157% (46%) deposition flux Mugagangqiong (Tanggula) ice cores...
Abstract In this work, the authors investigated spring dust storm frequency variations in northern China and its relationship with weather disturbances, cold high, eddy kinetic energy (EKE), as well impact of Arctic Oscillation (AO) on variations. It is found that there a significantly decreasing trend −26%/10 years addition, year‐to‐year are also remarkable, which account for 58.3% total variance The synoptic 850 hPa height, EKE, near‐surface highs highly correlated During last 40 or so,...
Abstract A model for source‐limited dust emission is proposed. The accounts the evolution of supply soil depleted by and enriched process surface renewal, together with several other new developments. tested a field dataset. impact source limitation to profound. Our tests show that considering limitation, predicted can reduce one order magnitude in real‐case simulation period less than 20 days. We much more complex variable considered previous models. findings have far‐reaching implications,...
Abstract The air pollution in Chinese Spring Festival (CSF) period over eastern China was investigated using the long‐term observations from 2001 to 2012 323 stations. dominant feature of pollutants around CSF holidays is significant reduction concentration. During 10day (but excluding Lunar New Year's Day, LNYD), PM 10 experiences a −9.24%. In association with aerosol reduction, temperature significantly drops China. From third day before LNYD second after, daily mean anomaly −0.81°C, and...
Abstract In this study, the possible influence of Antarctic oscillation (AAO) on winter haze pollution (indicated by atmospheric visibility after rain, fog, dust, snowstorms, etc. are removed) in North China (NC) was investigated. The results show that mean (December‐January‐February visibility) throughout most eastern is negatively correlated with preceding AAO (August‐September‐October (ASO)‐AAO), especially NC. interannual correlation coefficient between DJF‐VIS NC and ASO‐AAO −0.52,...
ABSTRACT The effects of El Niño/Southern Oscillation ( ENSO ) under negative Arctic AO phase on the Asian dust activity are investigated for springs period 1961–2002. spring index DI describing monthly frequencies three types events (e.g. storm, blowing dust, and floating dust) exhibits a significant increase in years (hereafter −) Niño, compared with that − La Niña. Averaged over all observation stations, (49.7) during Niño/ is higher by 11.4% or 29.8% than (38.3) Niña/ years. We suggest...
Abstract Eastern China has experienced substantial agricultural expansion and deforestation in recent decades. We modeled the influence of land use/cover changes (LUCCs) over eastern on regional climate using Weather Research Forecasting model with Noah‐multiparameterization surface scheme. Two 21 year (1980–2000) experiments were performed same settings, except for data 1980s 2000s. The results showed that northern China, decreases air temperature approximately 0.3–0.5°C (increases)...
