Assimilation of in-situ and satellite data in hydrological predictions – Can we add value?

Assimilation of in-situ and satellite data in hydrological predictions – Can we add value?

Contributed by Jude Musuuza (SMHI). The increased focus on satellite missions in recent years has resulted in a rich source of valuable Earth Observations (EO), in terms of spatial coverage and temporal frequencies that are impossible to achieve with direct measurements. Such observations have been used in various disciplines, including also hydrological modelling, for instance to improve process understanding through tailored model parameterisation and performance assessment. In addition EOs have been used to (better) initialise the model states which further…

Climate services help improve decision-making for weather-dependent industries

Climate services help improve decision-making for weather-dependent industries

Contributed by Ilias Pechlivanidis, SMHI, & HEPEX co-chair.  Many industries are in need of reliable and usable climate forecasts for the coming weeks and months. Such predictions can help energy companies and other weather-dependent sectors better manage climate-related risks.  Renewable energy – such as wind, solar and hydropower –  is the fastest growing source of electricity globally. Renewable energy comes from natural sources such as sunlight, wind, or rain, which are not continuously generated. The generation of renewable energy is…

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…

Flash flooding is a serious threat in the UK – here’s how scientists are tackling its prediction

Flash flooding is a serious threat in the UK – here’s how scientists are tackling its prediction

Contributed by Christopher J White, University of Strathclyde ; Michael Cranston, RAB; Laura Kelly, University of Strathclyde ; Linda Speight, University of Reading. It’s becoming a familiar scene on the news: sodden British people wading through streets up to their knees in flood water. From Stirling to Sheffield, many parts of the UK in 2019 felt the impact of severe surface water flooding – often referred to as flash flooding – that followed torrential rain. As the climate changes and the…

Protect your city from floods with the IMPREXive game

Protect your city from floods with the IMPREXive game

We all know that the HEPEX community loves games and interactive challenges. We have already six games available in our Resources page. One of these games (“Pathways to running a flood forecasting centre: an adventure game”, by Louise Arnal & colleagues) has inspired a very nice online game developed by Arctik, a public relations, communications and evaluation consultancy, within the EU Horizon 2020 Imprex research project. Do you want to play it? In the game, you’ve landed a job as…
