Short summary

The effects of aerosols on lightning are complex and still far from understood. We analysed the impacts of aerosols on lightning activity in the Sichuan Basin. Results show that lightning flashes first increase with aerosol loading during all periods and then behave differently (decrease in the afternoon and flatten at night). This suggests that the changes in solar radiation can modulate the aerosol effects on the occurrence and development of convection and lightning activity.
