With a south-westerly high-altitude current, air enriched with Sahara dust was also brought to Switzerland. A considerable amount of Sahara dust has ensured that the Sun’s rays and visibility have been severely restricted in recent days.
The Sahara dust and its effects were also clearly noticeable on the Jungfraujoch, as the pictures below show.
