The weather@home regional climate modelling project for Australia and New Zealand

Geoscientific Model Development (2016)

A new climate modelling project has been developed for regional climate simulation and the attribution of weather and climate extremes over Australia and New Zealand.

weather@home Australia–New Zealand (w@h ANZ), uses public volunteers’ home computers to run a moderate-resolution global atmospheric model with a nested regional model over the Australasian region.

This paper provides an overview of the w@h ANZ experiment, including initial evaluation of the regional model performance. The model is seen to be capable of resolving many climate features that are important for the Australian and New Zealand regions, including the influence of El Niño–Southern Oscillation on driving natural climate variability.
