Editorial statement

Downscaling climate predictions is an essential requirement for understanding regional climate impacts. This in turn is enabler for decision makers planning climate change adaptation. This paper demonstrates the utility of 12km ensemble climate simulations in providing useful predictions at a cost that enables ensembles large enough to capture some of the uncertainty. This paper is essential reading for those needing to understand the tools available for regional climate predictions.
