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

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…

Fictitious Forcings have Macondo in Trouble: A Hackathon Story

Fictitious Forcings have Macondo in Trouble: A Hackathon Story

Contributed by Georgy Ayzel.  Meteorological ensemble forecasts form the core of every system for hydrological ensemble prediction. There are multiple data sources where our meteorological ensembles could come from: historical observations, numerical weather prediction and climate models, or stochastic weather generators. Different sources serve different ways we want to communicate and deliver the information of possible runoff responses to various meteorological conditions. However, there is a source that is typically ignored in the modern landscape of ensemble runoff prediction –…
