Profile
Summary: 

Fredrik is a hydrologist by training and is now researching different aspects of weather-driven hazards with a focus on floods and droughts on the sub-seasonal to seasonal scale. Fredrik has over 10 years of experience from the field of operational probabilist forecasting and has worked on all parts of the modelling chain. He has also experience of hydrological climate impact modelling, statistical downscaling of precipitation model and uncertainty assessment. He is currently working at the operational centre of the Copernicus Emergency Service - Early Warning Systems (floods). He is a member of multiple professional bodies (HEPEX, British Hydrological Society, EGU). Fredrik Wetterhall is the author of over 50 peer-reviewed publications.

Professional interests: 
  • Operational probabilistic flood forecasting
  • Uncertainty in hydrological modelling
  • Sub-seasonal forecasting of droughts and water resources
  • Impact modelling
  • User understanding of probabilistic forecasts
