What is the value of seasonal forecasts for water resources management?

What is the value of seasonal forecasts for water resources management?

Contributed by Andres Peñuela, Christopher Hutton and Francesca Pianosi Improved skill of predictions for the North Atlantic circulation and Northern Europe have motivated an increasing effort to improve seasonal weather forecasting systems. Seasonal weather forecasts are expected to be useful for a range of purposes, including to improve the management of water resource systems. To contribute to the assessment of seasonal forecasts value for water managers, we ran a simulation exercise investigating how they could integrate seasonal forecast products in…

Playing ‘frisbee’ with seasonal predictions

Playing ‘frisbee’ with seasonal predictions

  Embed from Getty Images   This blog is written by Timo Kelder (@timokelder), a 3rd year PhD student in climate science at Loughborough University. Here, he writes about the history of frisbees, and the parallels with his recently published paper on using seasonal predictions for detecting recent trends in rare extremes. Ultimate frisbee is now a well-established sport, with over 70,000 British participants in 2019. The photo shows how this began in the 1970s by skimming disks. But how…

New water modelling to improve irrigation outlook accuracy

New water modelling to improve irrigation outlook accuracy

Contributed by Yating Tang1, Catherine Norwood2, Q J Wang1, Guy Ortlipp3, Mark Bailey3, and Kirsti Hakala1. Goulburn-Murray Water (GMW), Australia’s largest rural water corporation, has teamed up with researchers from the University of Melbourne to improve water forecasting in northern Victoria, to help irrigators with their business planning, cropping and water trading decisions. GMW is responsible for providing water availability information to local irrigators and other water users during the irrigation season each year. GMW provides two types of information…

Can seasonal hydroclimate services be a success story for local applications? Some answers based on a French case study!

Can seasonal hydroclimate services be a success story for local applications? Some answers based on a French case study!

Contributed by Louise Crochemore (SMHI), Ilias Pechlivanidis (SMHI) and Maria-Helena Ramos (INRAE). Hydroclimate services are increasingly available… An increasing number of hydroclimate services provide readily available water predictions to users at the catchment scale. For example, in Europe: Local to global services based on products from the Copernicus Climate Change Service (C3S) have been developed for the hydropower, water resources, flood risk prevention and agriculture sectors within the H2020 CLARA project. The H2020 S2S4E project has co-developed a decision support…

GloFAS-ERA5 reanalysis: River discharge ‘maps without gaps’ from 1979-present

GloFAS-ERA5 reanalysis: River discharge ‘maps without gaps’ from 1979-present

Contributed by Shaun Harrigan, ECMWF. In an ideal world we would have river discharge measurements for every river spanning many decades and updated in real time. We all know this is very far from reality with severe gaps in the global observing network (Lavers et al., 2019), and provides a fundamental challenge for hydrological monitoring and forecasting. A way forward pioneered in the field of meteorology and climate is to optimally combine available in situ and satellite Earth system observations…
