Met Office UK Weather Radar Network Upgraded

The Met Office have completed a £10 million pound state-of-the-art upgrade of the UK’s rainfall radar network.  For the first time the size and shape of raindrops and snowflakes can be captured, as well as wind speed data. These new scientific advancements have not only improved radar coverage but will lead to improvements in the accuracy of rainfall estimates, particularly during high impact weather events, such as flooding.

Extreme storms triple in Sahel due to Global Warming

Over the past 35 years extreme storms in the Sahel have tripled and it’s down to global warming, according to research conducted by NERC scientists at the Centre for Ecology and Hydrology. In such storms, clouds can grow to heights of 16 km and can produce substantial volumes of rainfall. Indeed, in 2009 one downpour deposited 263 mm of rainfall in several hours and forced 150,000 residents of Burkina Faso to leave their homes.
