Meteorological conditions during dust (PM10) emission from a tilled loam soil: Identifying variables and thresholds

•Relationships between weather variables and FVPM10 were analyzed on a loam soil.•Maximum wind speed and air humidity conditioned more significantly the FVPM10.•Were estimated threshold values of weather variables for FVPM10.•Crusting and surface aggregate size distribution influenced PM10 emission process.•Weather and soil surface conditions interaction produces high variability of FVPM10.
