What is the biggest change in the Met Office's new forecast system?

The Met Office's new forecast system is its biggest upgrade in three years, running on a powerful supercomputer that enhances prediction accuracy, especially for cloud and fog.

How far in advance will future weather forecasts be available?

Global weather forecasts will be extended to 10 days in advance, and local forecasts will be available up to 14 days ahead.

How does the new Met Office system improve rain and fog predictions?

The upgraded system better understands cloud microphysics, leading to more accurate predictions of when and where clouds, including mist and fog, form and improving rain forecast intensity.

UK Weather Forecasts Get Major Supercomputer Boost

The Met Office has unveiled a major upgrade to its weather prediction system, its most substantial enhancement in three years. This new model runs on a powerful supercomputer, improving the accuracy of forecasts for Britain's winter weather, especially concerning cloud and fog. Global weather predictions will now extend to 10 days, with local forecasts reaching 14 days, providing earlier warnings for events that could disrupt travel.

This advancement is crucial for the aviation industry, aiming to ensure safer take-offs and landings, fewer delays, and reduced cancellations. The improved accuracy stems from a better understanding of weather physics, particularly cloud microphysics, which helps in predicting water vapor condensation and precipitation more precisely. This means better identification of when and where clouds form, including low clouds and fog, which can significantly impact airport operations.
