Climate model biases and El Niño Southern Oscillation (ENSO) simulation US CLIVAR Variations

Over the last two decades the representation of ENSO in climate models has significantly improved, as documented by the extensive literature describing ENSO simulations in the Climate Model Intercomparison Project versions 3 and 5 (CMIP3 and CMIP5). Several aspects of ENSO, however, are still not satisfactorily represented in the current generation of climate models (Bellenger et al. 2014). In addition, as our understanding of ENSO and its complex coupled feedbacks deepens, we want any “realistic” ENSO simulations to be achieved as a result of a correct representation of those feedbacks, and not from compensating errors. 2015 OAR (Oceanic and Atmospheric Research) PSL (Physical Sciences Laboratory) GFDL (Geophysical Fluid Dynamics Laboratory) Submitted Other 1949
