Summer 2018 in Europe: did the EFAS seasonal outlook predict low river flows?

Summer 2018 in Europe: did the EFAS seasonal outlook predict low river flows?

— this post is jointly published on the blogs of HEPEX and the European Drought Centre — Contributed by Louise Arnal (ECMWF and University of Reading), Shaun Harrigan (ECMWF) & David Lavers (ECMWF). Summer 2018 in Europe was remarkable from a hydroclimate perspective, with large regions experiencing persistent dry conditions, very little to no rainfall for extended periods, a series of heatwaves with record-breaking temperatures and numerous wildfires (in the UK, Sweden, Greece, Spain, Portugal, Latvia and Germany, among others)….

Drought Monitoring and Prediction in South Asia

Drought Monitoring and Prediction in South Asia

Contributed by:  Vimal Mishra* and Saran Aadhar, Civil Engineering, Indian Institute of Technology (IIT) Gandhinagar, India Drought is one of the most complex natural disasters. In South Asia — a region including India, Pakistan, Bangladesh, Sri Lanka, Nepal, and Bhutan — increasing population, dependence on agriculture, and frequent droughts have resulted in water scarcity and food scarcity. In India, for example, about 330 million people were affected by the 2014-15 droughts, which led to severe water shortages (Mishra et al., 2016)….

Real-time forecasts for your holidays in Switzerland. Keep tuned and give feedback!

Real-time forecasts for your holidays in Switzerland. Keep tuned and give feedback!

In Switzerland the 1st of June represents the unofficial start of the flash-flood season. Against this, in 2013 we selected June 1st to launch our www.drought.ch platform on early recognition of critical droughts (see this post here). At that moment, a flood situation was going on in large parts of Switzerland (see our archived forecast here), and so less attention was given to that new product of us. This year I was planning to write sometimes here a blog post…

Streamflow flood monitoring and forecasting over Africa with little data

Streamflow flood monitoring and forecasting over Africa with little data

By Justin Sheffield (Princeton University) Recent flooding in Mozambique caused almost 100 deaths and displaced 150,000 people, with extensive damage to infrastructure. Forecasting such an event is a challenge because of the scarcity of on-the-ground data and lack of capacity in many parts of Africa, despite the great need. This post shows some results from the Princeton University African Flood and Drought Monitor (AFDM), which uses satellite precipitation and hydrological modeling to track large-scale surface hydrology, and weather/climate model output…
