of the underpinning science, evaluation and results; see the UKCP18 Land Science Report (Murphy et al, 2018). What is the NAO? The term ‘North Atlantic Oscillation’ (NAO) is used to refer to variations in the large-scale surface air pressure gradient in the North Atlantic region, which are responsible for much

Improving the impact of surface-based observations in our global and regional Numerical Weather Prediction (NWP) systems.

This area of research focuses on improving and developing the assimilation of a wide range of surface-based observations into both the global and UK regional Met Office Numerical Weather Prediction (NWP) models. Improving the assimilation quality in this way enables us to obtain the best possible

Our road surface forecast, designed specifically for the gritting and winter maintenance industry. 

Road surface temperatures can be different to air temperatures, so we provide site specific, road surface forecasts, designed specifically for the gritting and winter maintenance industry. This enables organisations to make the best safety decisions when temperatures drop and confidently identify

configuration of the Unified Model, covering the UK and Ireland, with hourly forecast data covering the period T+0 to T+48 hours, and 3 hourly forecasts out to T+120. With a resolution of approximately 0.018 degrees hourly data is produced at surface level and at standard pressure levels eight times

As low pressure parks up in the southwest for the next week, more unsettled weather is expected for many. However, mild southerly air means there will still be some warm sunshine on offer.

This weekend  Over the weekend, rain and showers are most likely across western parts of the UK and it will be windy at times too. A yellow warning for rain has been issued for much of Northern Ireland and western Scotland.   In the latest weekend weather forecast Alex Deakin said: “Low pressure

This week sees an improving picture, with high pressure becoming increasingly dominant over the weekend and bringing dry, more settled conditions for many. The change does happen slowly though. Wednesday sees a chilly start, with a warm front bringing showers to northeastern and eastern areas
