Winter storms in the German Bight are a significant coastal hazard in the southeastern North Sea. The authors use a model for enhanced seasonal forecasting accuracy. This enhancement focuses on storms identified by the highest wind speeds, determined using sea-level pressure data, during winter. The forecasting system, comprising 64 simulations initiated each November, aims to forecast these storms for winters spanning from 1960 to 2018. Initial forecasts for the first winter proved inaccurate. However, by concentrating on specific weather patterns in September and November linked to these storms, the authors refined their forecasting method. Selecting the most reliable simulations based on these patterns significantly improved the forecasting accuracy for winter storms, indicating enhanced predictability of major atmospheric changes. Their simulations might be applied to other similar applications.
