Abstract:
Aerosol-cloud interactions have significantly adjusted global climate change since the industrial revolution. However, understanding about aerosol-cloud interaction mechanisms still remains a low level, resulting in a large uncertainty in future projections of global climate change. Here, we reveal the crucial complex impacts of aerosols on clouds from shallow clouds to thunderstorms based on satellite observations, and further quantify their resulted radiative forcing, which counteracts a considerable portion of CO2 warming. This report will show how aerosols control the lightning amount and intensity of deep convective clouds. The same mechanisms affect the precipitation and radiative cooling effects of shallow clouds. Finally, we try to answer a question about how to use these principles of aerosol-cloud interactions to attempt artificial cloud seeding, thereby cooling our planet.
