A54C:
Identifying Links between the Large-Scale Atmospheric Circulation and Climate Extremes II


Session ID#: 10701

Session Description:
Extreme weather events are often accompanied by substantial economic, societal, and public health impacts. Accumulating evidence indicates that anthropogenic climate change has and will continue to alter the frequency and/or magnitude of some extreme phenomena. Much on-going extreme event research straddles the meteorological, climatological, statistical, and impacts disciplines, and offers an exciting opportunity for interdisciplinary collaboration. As atmospheric dynamics generally drive intra-seasonal to inter-annual surface climate variability, research identifying links between large-scale atmospheric circulation, modes of atmospheric-oceanic variability, and the occurrence of extreme events is at the fore of these interdisciplinary efforts. This session aims to bring together researchers investigating dynamical, ingredients-based, and/or statistical linkages between the large-scale circulation and extreme event occurrence on multiple temporal scales in the recent past and projected future.  We invite submissions that explore these linkages through various methods, including principal component analysis, pattern clustering, internal/external forcing attribution, extreme value statistics, and/or new mechanistic approaches.
