abstract = "Aerosol-cloud interactions remain the largest uncertainty in
climate projections. Ultrafine aerosol particles smaller than 50
nanometers (UAP<50) can be abundant in the troposphere, but are
conventionally considered too small to affect cloud formation.
Observational evidence and numerical simulations of deep
convective clouds (DCCs) over the Amazon show that DCCs forming in
a low aerosol environment can develop very large vapor
supersaturation because fast droplet coalescence reduces
integrated droplet surface area and subsequent condensation.
UAP<50 from pollution plumes that are ingested into such clouds
can be activated to form additional cloud droplets on which excess
supersaturation condenses and forms additional cloud water and
latent heating, thus intensifying convective strength and
precipitation. This mechanism suggests a strong anthropogenic
invigoration of DCCs in previously pristine regions of the
world.",
