Forecast Charts

Real-time observations can be used to generate a range of weather chart displays - showing current and immediate recent weather conditions and patterns. Forecast charts attempt to predict the future weather patterns and conditions - for the short (2 day) and medium term (3 to 7 day) future period.

Sophisticated computer analysis of the huge quantity of real-time data is used to create forecast charts. These show the predicted position of weather systems, from which deductions can be made about wind directions, wind strength, temperature changes etc. Forecast charts only show conditons for the short and medium term - long range forecasting is extremely difficult due to the large number of variable factors that affect our weather.

The European Centre for Medium Range Forecasting (ECMWF), based at Reading, UK, is a European Community weather analysis bureau, analysing data and providing regular forecast information for up to a week ahead.
