CLEX, the ARC Centre of Excellence for Climate Extremes

The Centre of Excellence for Climate Extremes (CLEX) is an international research consortium of five Australian universities and a network of outstanding national and international partner organizations supported by the Australian Research Council.

Climate extremes are the confluence of high impact weather and climate variability. The Centre will improve our understanding of the processes that trigger or enhance extremes and build this understanding into our modelling systems. The improved predictions of climate extremes will help Australia cope with extremes now and in the future.
