ACCESS-OM2-025 historical and twenty-first Century winds experiment, forced by CMIP5 historical and RCP8.5 winds.

To assess the wind contribution to future SST changes around Australia, we devise two wind perturbation experiments using ACCESS-OM2-025 model (Kiss et al 2020). These perturbations are initiated from an ACCESS-OM2-025 simulation equilibrated with CORE2-NYF atmospheric forcing, which excludes interannual atmospheric variability (Large and Yeager 2009).

The first experiment is a CMIP5 historical winds experiment (10 years output, ~125 Gb), where the CORE-NYF winds are replaced by the 1950-1969 average winds from an ensemble of 21 CMIP5 models. The second experiment is a CMIP5 end of 21st Century winds experiment (10 years output, ~125 Gb), where the historical CMIP5 winds are replaced by the average winds over the 2080-2099 period from the CMIP5 ensemble.
The CMIP5 historical wind forcing and CMIP5 21st Century wind forcing are calculated from a CMIP5 ensemble of 21 models. This ensemble shows poleward shifting Southern Hemisphere westerly winds over the southern Australian region from 1950 to the end of the 21st Century.
Python was used for all the data analysis.
The dataset was created by Earl Duran for the Centre of Excellence for Climate Extremes Climate variability and teleconnections research program.
