The Met Office and Microsoft are to build a world-leading supercomputer capable of providing more accurate warnings of severe weather as part of a multimillion-pound agreement.
It was expected to be the most advanced machine of its kind dedicated to weather and the climate, ranking among the top 25 supercomputers in the world and twice as powerful as any other in the UK, the Met Office said.
The supercomputer will have a 10-year lifespan and is due to start working from summer 2022, based in the south of the UK.
Britain has been trying to better prepare for the impact of increasingly extreme storms, floods and snow.
The technology will be able to produce more detailed models and improve local weather forecasting using high-resolution simulations, as well as supplying the aviation industry with more accurate forecasts of wind and temperature.
Penny Endersby, the chief executive of the Met Office, said people might not realise the full effects the supercomputer would have because it would help to prevent disasters such as flooding.
“In the short term, you will see a more accurate weather forecast that may be more detailed to your area and you may be able to tailor it more, but actually it impacts your lives
