- Impact of the ARI on the initiation of convection
Analyzing comprehensive aerosol and meteorological measurements in the boundary layer and WRF-Chem modeling, we found that the ARI affects both the initiation of convection and aerosol dissipation, leading to a delay in the onset of convective clouds.
- Impact of aerosol composition on the aerosol first indirect effects
Once a convective cloud is formed, its microphysical properties are affected by aerosol hygroscopcity and composition. Yet, estimation of this effect may differ systematically as inferred from satellite and ground-based measurements due to different regions to which the measurements are sensitive to.
- Joint impact of aerosol radiative effects and microphysical effects
Further development of a convective cloud is dictated by the joint effects of ARI and ACI. In the beginning stage of cloud development, aerosol radiative effects are dominant over aerosol microphysical effects, hence, aerosol perturbations suppress updrafts and precipitation. However, aerosol microphysical effects become dominant over aerosol radiative effects during the late stage of cloud development.
I will try to put these diverse, but inherently related, effects from a perspective of the lifetime of convective cloud system.
