• CTDE and instantaneous momentum flux are controlled by few atmospheric parameters, e.g. u*, w*
• Order of magnitude of CTDE is ~ 1-100 µg m-2 s-1
• Process of CTDE seems to be captured by parameterization
• Calculation of turbulent dust emission in regional model WRF/Chem_dust offers possibility of long-term quantitative estimates
