A43D:
Mechanisms of Anthropogenic Aerosol Forcing on Regional Climate Variability and Change II Posters


Session ID#: 8703

Session Description:
There is still large uncertainty in our understanding of regional changes in the climate system and of the extent to which they are influenced by humans. Aerosols, the largest forcing uncertainty over the industrial period, are particularly relevant since their forcing is spatially heterogeneous and might regionally largely offset that of greenhouse gases. By modulating radiation in the atmosphere and by altering cloud properties, aerosols affect surface and atmospheric heating gradients and precipitation distribution, which in turn lead to changes in the atmospheric circulation. These can extend the impact beyond the source regions. This session welcomes contributions from observations and modelling studies that contribute to improving the understanding of the mechanisms and pathways for the aerosol impact on regional climate worldwide. Studies focusing on changes in variability, long-term trends, and extremes in the hydrological cycle, in the recent past as well as the coming decades, are particularly solicited.
