ENS Products  - Their Use

The ENS produces a great deal of forecast data; much of it we display in chart form or as a diagram.  It is difficult for the human eye to identify more than the larger differences between each individual ensemble member so several display methods have been developed to enable critical assessment of the similarity and spread of results and to some extent the run-to-run consistency.  Chart output facilitates an easy visual interpretation of the information and a simple visual assessment of the probabilities of forecast weather events, and indeed of extreme weather events.  The outputs from the various IFS programs are described in the rest of Section 8 (HRES output & ENS output, Extended Range output, Seasonal output) .  Access to the charts (ecCharts, Open Access, Dashboard) is described in Section 10.
