PC44B:
El Nino-Southern Oscillation (ENSO) Diversity, Predictability, and Impacts IV Posters


Session ID#: 28002

Session Description:
The last three boreal winters in the tropical Pacific have exhibited an unlikely and confounding sequence of ENSO states. In the winter of 2014/15, a previously heralded extreme El Nio resulted in only a limited basin-wide warming. This was followed by an extreme El Nio event in the winter of 2015/16, which, however, did not have the strong eastern Pacific warming characteristic of previous extreme events. Also, unlike previous extreme El Nio events, a weaker than expected La Nia followed in 2016 accompanied by an intense warming near the coast of South America (Coastal El Nio) during the 2017 winter. In addition to the unexpected variability during these years, the impacts of ENSO in some remote locations deviated from expectations. These challenges highlight the need for a continued study of ENSO diversity, including its origin, predictability, global impacts, and interactions with anthropogenic climate change. We welcome observational, model, and paleo studies that focus on the challenges brought to light by the recent ENSO sequence, as well as studies of longer-term, multi-decadal ENSO variability, impacts of climate change on ENSO, and general ENSO dynamics.
