Met Office supercomputer makes better forecasts

The Met Office has launched its most significant scientific upgrade in more than three years, claiming it will producer more accurate forecasts that will be closer to real-world weather.

Forecasts will now more accurately show rain and snow in a way that more closely reflects real-world‑ conditions.

Improved weather modelling will also provide more accurate guidance on cloud and fog, which is particularly relevant for travel or journey planning. This advancement will be vital for industries such as aviation, where precise weather information is critical to manage flight schedules, avoid delays, and ensure safe take offs and landings, especially in situations with low cloud bases, mist and fog.

Colder season temperatures will now be forecast across the UK with greater precision, offering better support for gritting operations to keep road networks safe and operational. 

The upgraded system will deliver a clearer view of storm intensity around the world, strengthening global safety and humanitarian planning. It will extend our global forecasting out to 10 days, giving earlier insight into potentially disruptive weather. This will enable meteorologists to issue weather warnings further in advance.
