Selection of ensemble grid points for vertical profiles using the rule given above is illustrated below, using relatively complex but informative examples.

There can be inconsistencies in surface values because of different rules for selection of grid points for meteograms and vertical profiles. 

Fig9.9.2: Selection of grid points for vertical profiles.  Consider the four ensemble grid points that surround the location of interest.  The nearest grid point will be chosen regardless of being land or sea grid point. This means that vertical profiles at some coastal locations may not reflect the effects of the nearby sea or may not reflect the effects of the land.  Crosses represent grid spacing 0f 18km.  The colour scale represents the proportion of heat, moisture and momentum for each grid point derived by HTESSEL and Flake at 9km resolution.
