Modeling the Link Between ENSO and North Australian SSTs

In describing their results, the three Australian researchers report that: (1) "the CMIP5 models still show a wide range in their ability to represent both ENSO events themselves, and their relationship to north Australian SST," that (2) "most of the models fail to capture the strong seasonal cycle of correlation between the Niño-3.4 and north Australian SSTs," and that (3) "the models in general are still missing some underlying process or mechanism."
Catto et al. conclude by stating that "gaining a deeper understanding of the physical mechanism behind the strong link between the SSTs in the Niño-3.4 region and to the north of Australia using these models" is "a vital next step" for this work, which they say is required "to elucidate the processes missing from the models that cannot capture the link."
