I simulated the Föhn effect in the Cantabrian Mountains using the WRF (Weather Research and Forecasting) model, running the simulation on the supercomputer at the Galician Supercomputing Center (CESGA). The Föhn effect occurs when moist air ascends a mountain range, cooling and causing precipitation on the windward side, while descending dry and warm on the leeward side. I used global data from the GFS model, preprocessing it through WPS for my selected region. The simulation, spanning from March 8 to 11, 2018, recreated the conditions that trigger the Föhn effect, analyzing variables like relative humidity, temperature, and accumulated rainfall.
