A13H:
Cloud–Aerosol–Radiation–Climate Interactions in the Southeastern Atlantic II Posters


Submit an Abstract to this Session


Session ID#: 50411

Session Description:
Interactions between absorbing aerosol over and near clouds via radiative transfer, direct microphysical contact, or thermodynamic and dynamical processes impact climate. These cloud-aerosol-radiation-climate interactions are prevalent over the southeastern Atlantic, where large planetary low cloud decks, overlaid by biomass burning aerosol layers, occur. These reflective clouds help set the regional large-scale circulation. Smoke above clouds absorbs shortwave radiation and can produce a direct radiative warming when underlain by bright low clouds. The clouds are susceptible to atmospheric aerosol by changes in atmospheric stability and free-tropospheric moisture, and microphysical interactions. Both the low cloud deck and the smoke layer are challenging to measure and simulate at all scales, constituting a major uncertainty in understanding key processes and regional climate. Studies focused on all aspects of observation (in situ and remote sensing) and modeling of interactions between clouds, aerosol, radiation, precipitation, and climate over the southeastern Atlantic are solicited.
