What is a föhn wind, how does it form, and what impact does it have on humans?

Halny wind is a gusty and dry wind. It blows in southern Poland, strongest in the Podhale region, but also on the southern slopes of the Western Carpathians – in Slovakia and even in northern Hungary. It is created as a result of pressure differences between one slope and another, enters valleys and causes a significant temperature jump. This is associated with the occurrence of drought, faster snow melting, and faster ripening of plants.

Halny wind also has a very negative impact on humans – this phenomenon is called foehn (Fen is the general name for warm and dry wind blowing from the mountains into valleys). During strong halny wind, animals behave strangely, people are irritable, and it is easier to provoke a fight. People with depression experience more serious effects of this condition, and the number of suicides increases.

Halny wind usually blows for a few hours to 2-3 days. There is a recorded case from 1951 when the halny wind blew continuously for 11 days.
