Abstract The effect of anthropogenic warming on extreme rainfall events is a hot topic in this era global warming, and increasing attention being paid to its impact at regional local scales. We explore the localized response precipitation during high-impact “23·7” event Beijing–Tianjin–Hebei region under using ensemble convective-permitting simulations. identify two sub-regions with opposite responses: decreased (increased) northern (southern) sub-region area.

Recent advancements in artificial intelligence (AI) have notably enhanced global weather forecasting, yet accurately predicting typhoon intensity remains challenging. This is largely due to constraints inherent regression algorithm properties including deep neural networks and inability of coarse resolution capture the finer-scale processes. To address these insufficiencies we propose an attractive approach by initiating regional Weather Research Forecasting (WRF) model with Pangu-weather, a...

Accurate prediction of where and when typhoons (or named hurricanes which form over the North Atlantic Ocean) will make landfall is critical to protecting human lives properties. Although traditional method typhoon track based on steering flow theory has been proven be an effective way in most situations, it slipped up some cases. Our analysis long-term Chinese records reveals that typhoons, especially super (those with maximum sustained surface winds greater than 51 ms−1), have a trend...
