ENSO in the Pacific Basin: Insights from Proxy Records, Modelling Experiments, and Modern Climatology
Session ID#: 74077
Session Description:
Despite the global significance of the El Niño Southern Oscillation (ENSO), its response to different forms of climatic variability remains poorly understood. In order to respond and adapt to changes in the tropical Pacific driven by anthropogenic warming, we must contextualize modern ENSO activity by improving the pre-instrumental record of this phenomena. In this session, we welcome submissions from both proxy and modelling approaches aimed at identifying and quantifying shifts in the frequency, amplitude, and spatial patterns of the ENSO system, with an emphasis in the Pacific basin. Particularly of interest are studies which attempt to elucidate the geographic heterogeneity of ENSO events, or utilize multiple methodologies to reconcile different records from across the region. This session will involve contributions from climate modelling, proxy development, and modern meteorology, in an attempt to foster collaboration between disciplines and encourage a more integrated and holistic approach to understanding ENSO.
