The Met said the computer would create a "digital twin" of our atmosphere with data such as wind speeds, air temperatures and pressures, and more. Forecasts are made up to an area of only 1,000 meters (0.62 miles) compared to the current 10 km (6.2 miles). At large airports, the accuracy is concentrated to just 300 m. Once operational, not only will it make better forecasts (including rainfall forecasts), it will also help rescue workers deploy mobile flood barriers, balance the energy grid, and more.
The Met also found that it will also help services mitigate the effects of climate change "and help support the transition to a low-carbon economy across the UK," Endersby said. The supercomputer is also used by universities for drug design, AI, energy storage and other types of research.

The investment is by far the largest in Met's history, but the division believes it will make a big difference, giving an advantage of up to £ 19 ($ 23) for every pound spent. "We'll be ahead of all the other streets," said Met Met's CEO Penny Andersby. "Ultimately, it will make a difference for everyone, every government department, every industry, because the forecasts are getting better and better."
