A super dust storm enhanced by radiative feedback

Abstract As the main dust source area in East Asia, Gobi Desert (GD) exerts critical impacts on radiation budget downstream regions. Dust radiative feedback GD Mongolian cyclone, however, remains poorly understood. Herein, dynamic is coupled with Weather Research and Forecasting model Chemistry (WRF-Chem) for better simulations. Results show that cyclone dominates event May 2019. results downward momentum transport cools northeast of Mongolia by affecting zonal winds temperature advection. Lower-troposphere cooling upper-atmosphere warming change atmospheric vertical structure enhance baroclinicity. Further, cold air deeply descends into bottom warm a wedge shape promotes ascension to cyclone. The strong maintained continues cause high concentrations northern China via westerlies. This study explores how over can intensify provides scientific reference related studies.
