Can global warming bring more dust?

Abstract In the late twentieth century, global mean surface air temperature especially on land is continuously warming. Our analyses show that of dust increased since 1980, using Modern-Era Retrospective Analysis version 2 for Research and Applications (MERRA-2) reanalysis data. This variation mainly contributed by increase outside core areas (i.e. high mass concentration region). The causes to result in variations are explored. areas, wind primary driving factor dust, both which no remarkable trends or decrease 1980. arid semi-arid North Middle Asia, warming impact causing increase. An accompanied enhancement atmospheric instability can trigger more upward motion bring dust. All 9 Earth System Models (ESMs) Aerosol Chemistry Model Intercomparison Project (AerChemMIP) reproduce reasonable spatial distribution seasonal cycle present day. But only a few models such as BCC-ESM1 GFDL-ESM4 simulate increasing trend similar MERRA-2. While middle latitudes Eurasian continent, presented most ESMs.
