Model inventory

Data and charts from a wide range of leading Numerical Weather Prediction (NWP) computer models is available. NWP takes current atmospheric and ocean data and uses mathematical models to produce weather predictions.

Short range

Covering the 0 to 5 day period.

Medium range

Covering the 0 to 16 day period.

Ensembles

Covering the 0 to 35 day period. These are used to identify trends and probabilities at longer ranges.

Seasonal

Covering the 0 to 8 month period. Global seasonal models currently have a low skill level for the UK.

Multi model viewer

Many charts can be accessed using the original Chart viewer. However, due to the increasing number of models offered it is no longer feasible to make them all available.
