PC34B:
El Niño–Southern Oscillation (ENSO) Diversity in a Changing Climate III Posters
Session ID#: 11498
Session Description:
ENSO events differ in amplitude, spatial pattern, and temporal evolution. These event-to-event variations are difficult to predict and can result in markedly different global impacts. Moreover, tropical Pacific interannual variability appears to undergo decadal/interdecadal variations, which may obscure the detection of possible ENSO changes associated with global warming. In this session we welcome contributions that target the US CLIVAR goal of advancing our understanding of the origin, dynamics, impacts, and predictability of all aspects of ENSO diversity in a changing climate, using observations, theory, model simulations, as well as paleoclimate reconstructions. The unusual evolution of the 2014-2015 El Niño is a recent example of this diversity, and studies aimed at elucidating the physical processes underlying that event are strongly encouraged. We also welcome studies that clarify how model biases contribute to the diversity of ENSO representation among model simulations of past, present, and future climates, as well as research into how to reduce or otherwise cope with those biases.
