Multi-step evaluation framework for analyzing mineral dust transport and meteorological impacts over northern India
(2025) In Journal of Arid Environments 229.- Abstract
- Dust burden during the dust storms events imparts an adverse effect on human health and environment. The aim of this research is to provide a deeper understanding about the atmospheric dynamics of long-range transport of mineral dust for 8 severe dust storm events over the Indian region during the period 2008–2022. Transport of mineral dust analyzed based on MERRA-2 Dust column mass density, following a multistep evaluation process with individual datasets. Synoptic conditions inferred based on wind circulations patterns (200hpa and 850hpa) and mean sea level pressure. Semi-Direct effect of dust aerosol inferred based on the metrological conditions. Low pressure system and prevalence of stronger winds (>15 m/s) results in long-range... (More)

Transport of mineral dust analyzed based on MERRA-2 Dust column mass density, following a multistep evaluation process with individual datasets. Synoptic conditions inferred based on wind circulations patterns (200hpa and 850hpa) and mean sea level pressure. Semi-Direct effect of dust aerosol inferred based on the metrological conditions. Low pressure system and prevalence of stronger winds (>15 m/s) results in long-range transport of mineral dust. HYSPLIT Back-trajectory analysis and upper tropospheric circulations states the propagation of mineral dust from the dust prone regions. Enhanced dust loading (>0.89 × 10−3 kg/m2) is associated with reduced mid-tropospheric relative humidity and surface temperature. Higher aerosol loading (>1.0) combined with a low Ångström exponent (<0.6) values indicate the presence of coarse-mode dust particles in the atmosphere. The presence of elevated absorbing aerosols leads to atmospheric heating and moisture suppression in the mid-troposphere, reflecting the semi-direct effect of dust aerosols over Northern India.
