UK to spend $1.6 billion on the world's fastest weather supercomputer

The UK's weather service, the Met Office, will spend £1.2 billion ($1.6 billion) to acquire the world's most powerful climate supercomputer, the government has announced. That's over ten times more than its current Cray XC40 cost, but it will deliver more timely and accurate forecasts. That could make the difference in knowing whether your flight will be canceled or your street flooded, according to the service. The Met said the computer will create a "digital twin" of our atmosphere with data like wind speeds, air temperatures and pressures, and more. It will create forecasts down to an area just 1,000 meters (.62 miles) across compared to 10 km (6.2 miles) currently.
