Watch the Webinar: Linking global warming with recent trends in intense storms in West Africa
This webinar (30 min presentation & 10 min Q&A session) by Meteorologist Prof. Chris Taylor provided an introduction to the work of the AMMA-2050 consortium, insight into the rapid increase in intense Sahelian storms observed in recent decades, and how continued climate change will influence flood risk in the region.
The webinar was held on 18th January 2018 and you can watch a recording below;
The UK-based Centre for Ecology & Hydrology (CEH) has led an international team of scientists who reveal global warming is responsible for a tripling in the frequency of extreme West African Sahel storms observed in just the last 35 years. The research falls under FCFA’s AMMA-2050 consortia which is working to improve understanding of how the West African monsoon will be affected by climate change in the coming decades – and help West African societies prepare and adapt.
The study (see Nature for the original paper) has analysed trends from 35 years of satellite observations across Africa, and provides unique insight into how some of the most violent storms in the world are responding to rising global temperatures.
The Sahelian storms are some of the most explosive storms in the world, containing clouds that can grow to a height of 16km above the ground. In 2009 a downpour of 263mm over several hours forced 150,000 residents of Ouagadougou, in Burkina Faso, to leave their homes.
