The study looked at different ways to predict how much rain falls in different parts of the UK. By using more than one type of information, like elevation, the predictions were more accurate. They found that using a local model for predicting rain amounts was better than using a one-size-fits-all model. Also, using multiple types of information together gave better predictions than just using one type. Overall, combining different methods and using local models can help make more accurate predictions of rainfall in the UK.
