Aerosol invigoration and restructuring of Atlantic convective clouds
[1] Clouds and precipitation play crucial roles in the Earth’s energy balance, global atmospheric circulation and the availability of fresh water. Aerosols may modify cloud properties and precipitation formation by modifying the concentration and size of cloud droplets, and consequently the strength...
