The study looked at how a weather model called WRF can help predict changes in temperature and rainfall in Western Australia. By testing different input data and model settings, the researchers found that using certain data sources and model options improved the accuracy of the predictions. For example, using a specific analysis dataset led to better simulations of rainfall and temperatures. They also found that using a certain scheme for cumulus clouds and a specific model for radiative transfer improved temperature predictions. Overall, the study shows that WRF can be a useful tool for understanding how climate factors like temperature and rainfall may change in the future in this region.
