As part of the NSW/ACT Regional Climate Modelling (NARCliM) project three model configurations of the Weather Research and Forecasting (WRF) model have been chosen based on performance and independence. The independence measure is based on the covariance of model errors and ensures that error characteristics differ between the configurations. Each configuration has been run for 60-years over the CORDEX-AustralAsia domain driven by the NCEP/NCAR reanalysis. This talk examines the performance of these WRF configurations over Australia. Results demonstrate the independence of the model errors. Further examination of the teleconnections with large scale climate modes (e.g. El Nino) and trends in extremes generally demonstrates that the regional models perform better than the driving reanalysis. These improvement vary between configurations.
