The map displays valley wind systems and their directions of flow on normal/light-wind, thermic days. The majority of the information was painstakingly collected with the help of locals and after a protracted process was worked up and published. Despite this, the complexity of the weather means it is possible that not all valley winds have been included or that one or more of the arrows is not completely accurate. There are clear areas and less defined zones, where changes may occur throughout a given day. Some areas are more or less affected by large-scale weather patterns or strong supra-regional met winds.
This map is intended to assist with getting a bigger picture, seeing connections, recognising sensitive areas and therefore to be able to understand what is happening in the atmosphere and how to read the terrain. Steep slopes, areas of convergence and lee areas are immediately identifiable.
normal valley wind up to 20 km/h with direction (thin arrow)
strong valley wind over 20 km/h with direction (thick arrow)
Lee side areas: Strong valley wind systems (e.g. Bavarian wind) often flow over slopes or ridges and create unpleasant lee side areas. We have marked many, but not all, sensitive areas.
Known house thermals: the marked thermal sources are known and popular hotspots, which depending on the time of day, will produce more or less lift.
