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)….

10 years of the Sub-Division on Hydrological Forecasting at EGU (2008 – 2018)

10 years of the Sub-Division on Hydrological Forecasting at EGU (2008 – 2018)

Contributed by Maria-Helena Ramos and Femke Davids The field of Hydrological Forecasting has grown over the last ten years into an interesting and thought-provoking sub-division to the European Geosciences Union (EGU). Through this sub-division, at one of the largest Geoscience conferences in the world, we address many challenges that today’s hydrologists, and also users and decision-makers in the water sector, have to deal with. Below you will find an interesting read into the background and history of this field at…

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…

Risk Communication for Cyclone Early Warning – Do people get the message, and understand what it means for them?

Risk Communication for Cyclone Early Warning – Do people get the message, and understand what it means for them?

Contributed by Bapon Fakhruddin, Senior DRR and Climate Resilience Specialist, Tonkin+Taylor & Co-chair of the Risk Interpretation and Application of IRDR/ICSU Every year, New Zealand is impacted by ex-tropical cyclones (ETCs) – typically, one ETC makes landfall per year, between the months of November and April. As tropical cyclones approach New Zealand, they begin to lose their strength and undergo extratropical transition (ETT). Some of these weather systems are as large as New Zealand’s North Island when considering the full diameter…
