The Effect of Anthropogenic Aerosols on Past and Future Regional Climate
Session ID#: 76119
Session Description:
Anthropogenic aerosols play a key role in driving climate anomalies over a range of spatial and temporal scales. Aerosols can interact with radiation and clouds, directly and through absorption, microphysics and circulation, and thereby modify the surface and atmospheric energy balance, cloud dynamics and precipitation patterns, and the atmospheric and oceanic circulation. The climate response pattern results from the interaction of a variety of processes, feedbacks, and compounding pathways, which all contribute to make it difficult to identify and quantify the aerosol imprint. This session welcomes contributions focused on the understanding of mechanisms and pathways for the aerosol impact on past and near-future climate worldwide, in models and observations. Topics may range from climate extremes to decadal variability, such as on the tropical circulation and the ITCZ, mid-latitudes and the Arctic, tropical-extratropical interactions and teleconnections, and the interaction with modes of variability such as the NAO, AMO, and PDO.
