Short summary
This study explores how a powerful storm like Anatol, which hit Denmark in 1999, could change in a warmer future climate. Using a weather model, the storm was simulated under future temperature conditions. Results show stronger winds affecting larger areas for longer periods. A new index was introduced to measure storm severity. The findings highlight the growing risks to infrastructure and the need for better storm preparedness.
