Short summary
This study investigates the relationship between the size of windblown dust aerosols and wind conditions over topography at a regional scale, utilizing 10 years of dust reanalysis data. Linear regression and machine learning models suggest that greater wind speeds and land slopes, particularly under uphill winds, are associated with increased fractions of coarser dust. Moreover, these positive correlations weaken during summer and afternoon events, probably related to the haboob storms.
