The impact of climate change on hydropower production in Switzerland revealed substantial uncertainties related to the water resources that will be available in 30 to 50 years. SCCER-SoE aim at leading research in climate modelling, glacier and snow research to significantly reduce these uncertainties and provide a more secure basis to hydropower industry to decide on long-term investments. The project is part of Task 2.1: Morphoclimatic controls on future hydropower production.
Project details: Generation of very high-resolution climate scenarios for hydropower projection – addressing climate uncertainty and extreme events
The main objective of this project is to generate very high-resolution climate scenarios for hydropower projection for the mid and end of the 21th century using state of the art global and regional climate models and greenhouse gas scenario ensemble. For that purpose a new stochastic weather generator is being developed with the aim of formulating a high spatial and temporal resolution (e.g. 1 km x 1 km and 5 min) for simulating key climate variables (e.g. precipitation, temperature, cloud cover, etc.) at local scale and over a raster. This will allow better exploring the uncertainties in the projected climate scenarios at basin scale, which result from emission scenarios, natural-stochastic climate variability, and global circulations models.
