Katabatic wind

[8] Katabatic winds are for example found blowing out from the large and elevated ice sheets of Antarctica and Greenland.

[10] In Greenland these winds are called piteraq and are most intense whenever a low pressure area approaches the coast.

Williwaws originate in the snow and ice fields of the coastal mountains, and they can be faster than 120 kn (220 km/h; 140 mph).

[11] In California, strong katabatic wind events have been responsible for the explosive growth of many wildfires, including the 2018 Camp Fire and the 2020 North Complex.

In Catalonia, the Marinada is a fall wind that relieves from the heat inhabitants of the Urgell region during summer.

Plateau-cooled air falls into the Makhtesh Ramon , traced by radiation fog , just after dawn. Radiative cooling of the desert highlands chills the air, making it more dense than the air over the lowlands. Cooler air can also hold less water vapour ; it condenses out as tiny fog droplets, which re-evaporate as the air warms. Here, the falling air is warming adiabatically , and so the fog re-evaporates as it falls. [ citation needed ]
