CLEX, the ARC Centre of Excellence for Climate Extremes

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

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 enable improvements in how Australia copes with extremes now and in the future.
