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)….

Skilful seasonal forecasts of streamflow over Europe?

Skilful seasonal forecasts of streamflow over Europe?

Contributed by Louise Arnal, University of Reading & ECMWF Editor’s Note: Don’t miss the brilliant cartoon summary at the bottom of this post! Over recent decades, seasonal streamflow forecasting methods have evolved and diversified, reflecting changes in our scientific understanding of streamflow predictability on seasonal timescales and our increasing computer power. The first operational model-based ensemble seasonal streamflow forecast, called the ESP1,2 (ensemble streamflow prediction), relies on the correct knowledge of the initial hydrological conditions (IHC; i.e. of snowpack, soil…

Forecasts of water variables – interview with Ilias Pechlivanidis

Forecasts of water variables – interview with Ilias Pechlivanidis

I can’t exactly remember the first time I met Ilias, but I can remember that every time we have the opportunity to sit together, we end up having great talks about hydrology, modelling and Greece (including its food/drink specialities and beautiful places to visit!). Ilias is a senior hydrologist at the Swedish Meteorological and Hydrological Institute (SMHI) since 2012. He has broad experience in hydrological modelling and forecasting, and has been recently appointed Scientific leader of the theme “Forecasts of…
