Weather situation
The Omega weather situation is characterized by a high-pressure bridge over Central Europe, which tends to assume a stationary and therefore blocking state. Mild and dry air masses of subtropical origin are brought in from the south-east. It is a gradient-weak situation, i.e. pressure differences and the resulting currents are weak, and ultimately high fog and inversions are on the horizon in the early winter and therefore low-radiation season. In the Sentinel-2 satellite image, we can therefore identify distinctive fog patches over Lake Geneva.
