ACCESS-ESM1.5 in idealised worlds
We will run 300yrs long simulations with the ACCESS-ESM1.5 in which the land-ocean distribution is idealised to study ENSO and tropical basin interactions. We will do several such experiments with different land-coean configurations.
The aims are:
(1) Extend the capability of ACCESS for blue sky research
(2) Test ENSO theories.
(3) Build a basis for deep paleo studies.
Scientific motivation:
In a recent study such experiments have been done with a low-resolution GFDL model that resulted in highly interesting outcomes for ENSO theory and tropical basin interactions. They challenge our understanding of ENSO dynamics. See reprint:
