Forecasting System (IFS)
Section 2 describes in broad, non-technical terms the ECMWF IFS (the global atmospheric model, the wave and the oceanic dynamical models, and the data assimilation systems). It gives an overview of the way the atmospheric model uses sub-gridscale parameterisations for processes within the atmosphere and at the surface. There are large differences in energy fluxes between land or sea and the atmosphere, and the definition of the model coastline by the land-sea mask is extremely important, not least in the way data is presented (e.g. for meteograms in coastal areas or on islands).
