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…

Hydrological Forecasting at Virtual EGU 2021

Hydrological Forecasting at Virtual EGU 2021

The EGU 2021 Annual General Assembly (vEGU21) will take place from 19–30 April 2021, and due to the challenging Covid-19 situation, this event will be a virtual one. We shall nevertheless grasp all opportunities to get updated on the recent scientific insights and developments and also to virtually socialize with friends and colleagues. To suport the EGU HS Hydrological Forecasting subdivision efforts and make vEGU21 a big success this year too, see below the sessions that are relevant to HEPEXers….

Celebrating the new hydrological year with a new HEPEX blog year: Let’s co-generate the HEPEX blog global pattern

Celebrating the new hydrological year with a new HEPEX blog year: Let’s co-generate the HEPEX blog global pattern

Happy New Hydrological Year!! According to USGS and based on meteorological and geographical factors, the hydrological year is defined as the period between October 1st of one year and September 30th of the next year. Driven by this, HEPEX will set for this year a new interactive approach for scheduling the blogs with and for the community. The blog has been our channel to communicate scientific achievements, insights and developments. As a blogger, you do not need to be outstanding…

“Are we talking just a bit of water out of bank? Or is it Armageddon?” Front line perspectives on transitioning to probabilistic fluvial flood forecasts in England

“Are we talking just a bit of water out of bank? Or is it Armageddon?” Front line perspectives on transitioning to probabilistic fluvial flood forecasts in England

Contributed by Louise Arnal, Jess Neumann, Liz Stephens and Hannah Cloke This blog post is based on a paper recently published in Geoscience Communication, written in collaboration with Liz Anspoks, Sue Manson, Tim Norton and Louise Wolfenden from the Environment Agency. With the aim to better anticipate future floods, UK policy is seeing an ongoing shift from flood defence towards a forecast-based flood risk management approach, under the Flood and Water Management Act 2010. It is in this context that…

Can we achieve seasonally coherent forecasts given limited NWP DATA – across a continental domain?

Can we achieve seasonally coherent forecasts given limited NWP DATA – across a continental domain?

Contributed by Kirsti Hakala1, QJ Wang1, Qichun Yang1 and David Robertson2. Reliable weather forecasts are critical for the planning and management of a variety of social and economic activities, such as water management. To make such forecasts, numerical weather prediction (NWP) models have been developed. However, NWP models are limited in their ability to represent certain physical processes and initial conditions, and thus include inaccuracies, which can be improved through calibration. Effective calibration should aim to provide forecasts that are…
