Outlook models

Numerical Weather Prediction (NWP) is the basis of short and medium range weather forecasting. Powerful computers crunch large amounts of current weather data from around the globe and apply the laws of atmospheric physics to it to project the likely evolution. On TheWeatherOutlook the NWP model we primarily use is the Global Forecast System (GFS) and detailed data from it can be viewed here. On this page we provide external links to data from other NWP models.

Key

  1. ECMWF - European Centre for Medium-Range Weather Forecasts
  2. Fax charts - These are produced by the UK Met Office
  3. UK Met Office - Data from the UK Met Office's own NWP model
  4. GFS Ensemble line graph - another way to view ensemble data from the GFS
