Data Drought and Data Flood

Data Drought and Data Flood

Contributed by Mark Trigg*.  It’s hot, and very, very dry. The rains have failed, and the animals are dying. Around the table people are concerned that it will be people dying next. The cycle seems to repeat every 10 years and the response is exactly the same, every time – we must do something and save lives. “Drill more boreholes and put in big pumps and generators”, someone cries, “no matter the cost!”. A timid voice rises above the ongoing…

Drought Observatory: a Climate Service to improve environmental resilience

Contributed by Ramona Magno, IBIMET-CNR, Italy. Drought is a creeping and complex phenomenon with different types of impacts that imply a general reduction of water availability and involve either energy or food sectors, and on a wider scale the ecosystems. Under a climate change framework, the increasing frequency of droughts and their extended persistence need to be accounted for, addressing both adaptation and mitigation strategies. Drought dynamics reveal a time gap between the onset of a drought event and the…

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…
