Over the past two decades, the northwestern and northern India semiarid regions have experienced widespread hail events during the winter season, which can adversely impact agriculture and lead to economic losses. While rainfall and snow events over north India are typical, the occurrence of intensified hail events in winter is unique and requires an understanding of their intensification mechanism and prediction. In this study, we examined the role of winter aerosols in enhancing rainfall and hail processes and the associated mechanisms. The hail and rainfall processes are triggered by the storm system associated with the western disturbance (WD). Satellite observations indicated that the aerosols in the Indo-Gangetic Plains (IGP) were transported toward northwest India, and this transport was instigated by the WD-associated wind circulation. The transported aerosols induce aerosol radiative effects by warming (cooling) the atmosphere above (below) the aerosol layer. In response to the warming of the aerosol layer, cyclonic circulation aloft intensifies to enhance moisture convergence, leading to an increased concentration of cloud droplets and ice particles. Using 3-km high-resolution convection-allowing simulations, we explored the implications of aerosol radiative effects in winter on hail formation. Our model experiments show an increase in the rainfall and hail with an increase in aerosol concentration over north India. As a result, the radiative effect of aerosols boosts the atmospheric circulations associated with WDs, which in turn affects the intensity and dynamics of extreme weather events like hailstorms.
