@Gkikas-LGPZ , yes...believe it or not...ive never encountered such a feature of calm wind, but some of the polar lows straying my coastal areas has that too, extremely exciting, with large sea waves, and no wind... so i would consider those deadzones of calm as actual and not just an impostrous graphic from the modelmakers ørjan

@hidicker Unfortunately, we don't have any specific computation as a reson from them to share.
