8 Conclusions

Wind simulation has improved significantly using NWP models at convective scales. This is specially the case when orographic processes play an important role. These models generally represent deep convection explicitly having more chances to improve the circulations associated with convection but it should be taken into account that these resolutions are still too broad to resolve completely deep convection. When convection takes place, the predictability decreases and it is advised to follow ensemble approaches to estimate the prediction uncertainty.

The complexity of surface processes is large, in particular in the representation of the wind profile. Different surface covers are taken into account being particularly important the representation of vegetation effects and the presence of water, sea/ice, or urban surfaces. There is no general consensus about the need of an effective roughness length or a subgrid scale orographic parameterization to enhance the orographic effects at convective scale NWP modeling.
