|a Aerosol indirect effects, i.e., the interactions of aerosols
with clouds by serving as cloud condensation nuclei or ice
nuclei constitute the largest uncertainty in climate forcing
and projection. Previous IPCC reported negative aerosol
indirect forcing, which does not account for aerosolconvective
cloud interactions because the complex processes
involved are poorly understood and represented in
climate models. Here we elucidated how aerosols change
convective intensity, diabatic heating, and regional circulation
under different environmental conditions. We found
that aerosol indirect effect on deep convective cloud systems
could lead to enhanced regional convergence and a
strong top-of-atmosphere warming. Aerosol invigoration effect
occurs mainly in warmed-based convection with weak shear.
This could result in a strong radiative warming in the atmosphere
(up to +5.6 W m-2), a lofted latent heating, and a
reduced diurnal temperature difference, all of which could
potentially impact regional circulation and modify weather
systems. The positive aerosol radiative forcing on deep clouds
could offset the negative aerosol radiative forcing on low
clouds to an unknown extent |
