The study evaluated the Weather Research and Forecasting (WRF) model's ability to simulate short- and long-term thermal and hydrological conditions in Europe. They optimized the model's performance by testing different parameter combinations and spatial resolutions. Results showed that using a resolution smaller than 10 km did not improve model performance but increased computational costs. For extreme rainfall events, a multi-criteria analysis was necessary for accurate predictions. The model effectively simulated climate variations using NASA GISS ModelE2 data and dynamic scaling techniques. Winter had the largest deviations in southwestern Europe, while spring showed the lowest regional discrepancies due to less snow cover and milder radiation effects compared to summer.
