Introduction
The CMIP7 Fast Track is designed to be a targeted set of experiments that are run in time for inclusion in the next IPCC Assessment Report. ACCESS-ESM1.6 is Australia’s submission to this. -
Methodology
In this talk we will present a preliminary evaluation of the model’s preindustrial spinup run, focussing on properties of large scale modes of variability such as the El Nino Southern Oscillation, Indian Ocean Dipole, Southern Annular Mode and others. We will evaluate their teleconnections to global and Australian temperature and rainfall. Output from ESM1.6 will be compared to both observations and the preindustrial run of ESM1.5. -
Results
The ability of the model to simulate these large scale modes of variability and their teleconnections is of extreme relevance to the Australian modelling community. Up to 50% of Australian rainfall in some regions is influenced by these modes, so the ability of the model to capture the temporal and spatial properties of these relationships is of great interest.
