Keynote talks

Upskilling – Uncertainty reduction and representation in seasonal forecasting

QJWangBy Dr. QJ Wang, senior Principal Research Scientist, CSIRO, Australia:

“I will share with participants on the various methods we have developed to improve forecast skill and reliability, extend forecast range, and make forecast products more tailored to user needs in Australia” Read more about QJ Wang


Hydrological Outlook UK: an operational river flow and groundwater level forecast at monthly to seasonal scale

ChristelPrudhommeby Christel Prudhomme, CEH, UK:

“I will talk about the Hydrological Outlook UK, which is the first operational forecast system for Great Britain that delivers monthly outlooks of the water resources for the next 1 to 3 months for both river flow and groundwater levels. It is based on an expert-merging of three complementary methods: a statistical method based on river flow analogue and persistence; a Streamflow Ensemble Prediction System applied to selected catchments and boreholes; and a national hydrological modelling system driven by rainfall scenarios based on the UK Met Office ensemble rainfall 1 and 3 months forecasts.”Read more about C. Prudhomme


Processing weather forecasts for hydrological ensemble forecasting and decision making in hydropower

ET-StatkraftBy Erik Tjøtta, Statkraft Energi AS, Norway:

“In the presentation we outline how information from weather forecasts for various horizons can be combined, using quantile mapping, and processed through the models to produce a seasonal hydrological ensemble forecast.Read more about Erik presentation

Seasonal forecasting is increasingly becoming part of water management activities and tools. This workshop will bring together researchers, operational forecasters, practitioners and end-users from all around the world to discuss the latest developments in hydrological seasonal forecasts and applications in the water management sector.

The workshop is free of charge and will start on Monday morning, 21 September and end at midday on Wednesday, 23 September. For information on accommodation and travel, please see below.

Following the workshop, 24-25 September, the annual HYPE course Multi-basin modelling at the large scale using HYPE will be held at SMHI. The focus of the course will be on: processes in the cold regions (ice, snow) and spring flood forecasting. More information about the HYPE course you find here.

Workshop themes

The workshop will be organized in 6 themes with panel discussions, oral presentations, poster sessions, and lots of opportunity for discussions and sharing of experience:

  1. User needs of seasonal forecasts (hydro-power, groundwater, agriculture, insurance companies, health, safety-risk reduction)
  2. Statistical, dynamical and hybrid systems for predicting seasonal meteorological and hydrologic variables
  3. Progress in sub-seasonal to seasonal prediction
  4. Pre-processing, post-processing and calibration methods to enhance seasonal forecasting skill (data assimilation, initialisation, hindcasts)
  5. Communicating seasonal meteorological and hydrological forecasts  in water management and risk-based decision making
  6. Examples of climate and water services providing and using seasonal forecasts
