A050:
Improving our Mechanistic Understanding of the Regional Climate Response to Anthropogenic Aerosols





Session ID#: 23617

Session Description:
The extent to which regional changes in the climate system are influenced by anthropogenic aerosols is not yet well understood. Aerosols, the largest forcing uncertainty over the industrial period, are important since their forcing is spatially heterogeneous and can counteract greenhouse gas forcing. By modulating radiation and altering cloud properties, aerosols affect surface and atmospheric heating gradients and precipitation, and further result in atmospheric circulation changes. The objective of this session is to improve the understanding of mechanisms and pathways for the aerosol impact on regional climate worldwide. Observational and idealized/comprehensive modeling studies focusing on changes in variability, long-term trends, and extremes in the hydrological cycle, in the recent past and in near-future projections, are particularly solicited. We encourage papers investigating the impact of aerosols on monsoon systems, ITCZ, tropical-extratropical interactions and teleconnections, modes of variability, and the role of local versus remote aerosol emissions.
