A dynamic new climate model has been developed with the help of AARNet. With greater resolution than other models, it’s helping Australia cities protect and plan for the changing climate.

Australia’s environment is set to change rapidly over the next few decades. Temperatures are increasing, and more extreme weather events are predicted. This will impact every part of Australian life, from our cities, to our water supply and our environment. Because of this, it’s vital that Australia prepares for its future climate.

Professor Jason Evans of the Climate Change Research Centre and the ARC Centre of Excellence in Climate Extremes has developed a new climate model that predicts changing weather patterns with greater resolution. Professor Evans’ model predicts weather patterns down to 50km2 across Australia, even to a resolution of 10km2 in Australia’s heavily populated south east.

Climate simulations require huge amounts of data processing. Interactions between particles micrometres in length affect kilometre-long cloud movements across the entire planet. To get a truly accurate dynamic model, all this data needs to be considered.

Professor Evans’ research requires large amounts of data output from Pawsey Supercomputing Centre and National Computational Infrastructure (NCI) to be transferred across the country and to his team at the University of New South Wales (UNSW). The data requires real-time streaming to allow simulations to run. To make this possible, AARNet’s Advanced Research Network connects all three institutions for high bandwidth data transfer.
