A Month of Storms: Ciara, Dennis and Atmospheric Rivers

Contributed by Helen Griffith, Dept of Geography & Environmental Science, University of Reading, UK. February 2020 has been announced as the wettest February on record for most of the UK[1]. The arrival of Storms Ciara and Dennis led to widespread flooding and the recovery is expected to cost the insurance industry over £225m[2].

OpenIFS@home: Using citizen science to improve our understanding of weather and hydrological forecasts

The history of HEPEX is deeply connected to ensemble forecasting and uncertainty analysis. Indeed, none of us could even imagine a forecast without uncertainties (apart from McFool). One direction of research is to investigate the value in improving forecasts using a coupled system and truly understand the interactions between the atmosphere and the land surface whilst analysing the associated uncertainties. However, any analysis is limited by the resources one has available. To run a large number of ensembles, one would…

Integration of Early Warning Systems and Young Professionals

Contributed by Nilay Dogulu, Lydia Cumiskey and Erika Roxana Meléndez Landaverde Early warning systems (EWSs) help society to prepare for, and respond to, all types of disasters, including those related to hydrometeorological hazards. The recent floods in Mozambique has clearly showed that EWSs are inevitable part of disaster risk management as they can save lives and minimize potential economic and environmental damages. The Sendai Framework for Disaster Risk Reduction 2015–2030 specifically emphasizes the need to “substantially increase the availability of…

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…
