Joran and Scirocco
Depending on the position of the high- and low-pressure areas, the wind can turn more towards a northwesterly or northerly direction, in which case, the air will be colder and less humid. If a cold front passes through with a northwesterly flow, the cold air sinks along the southern foothills of the Jura, producing occasionally strong gusts. This northwesterly wind is called a Joran.
On the other hand, the flow may turn in a more southwesterly to southerly direction. In this case, the air is more humid and mild. If the current turns more towards the south, the Scirocco sometimes blows in Ticino. This warm wind is associated with heavy precipitation that builds from the Mediterranean Sea.
Southerly and northerly Foehn
If the flow turns in a southerly direction, this results in a southerly Foehn in the Alpine valleys on the northern side of the Alps. Conversely, the northern Foehn blows in the alpine valleys on the southern side of the Alps when the flow is directed towards the north. Foehn is a warm, dry wind.
