Two types of interpolation with the NCEP data were performed:
linear interpolation in time and double linear interpolation in space.
This led to hourly NCEP wind fields in a grid of 0.5°×0.5°, which
corresponds to the same resolution of the REMO wind fields. Therefore
the matching co-ordinates of NCEP fieldswere then replaced with
the REMO fields, as can be seen in Fig. 1. The final wind grid has 173
longitude points and 117 latitude points (Table 1).
