The relationship between aerosol and lighting has been identified using aerosol optical depth (AOD), meteorological, and climate parameters from 2017 to 2020 to investigate aerosols’ effect on electrical activity over India’s southern parts. The study’s outcomes concluded that an increase in the concentration of AOD supports the number of lighting activities. The remarkable regional difference was observed over India’s southern part by using correlation analysis between AOD and meteorological and climate parameters at a different spatial distribution. The microphysical effect of aerosol on the charge distribution in thundercloud may explain. The onset of monsoon rainfall causes a drastic decrease in AODs due to wet removal, whereas the buildup in AODs during the dry season is gradual. More available moisture as per the climatological and elevation conditions, have greater effect on the lightning activity. This study aims at examining the correlation between, AOD, precipitation and lightning activity through spatio-temporal analysis in wet and hot humid tropical zones in the southern parts of India.
