Košava (Serbian Cyrillic: Кошава, pronounced [kɔ̌ʃaʋa]) is a cold, very squally southeastern wind found in parts of Eastern Europe and the Balkans.
It starts in the Carpathian Mountains and follows the Danube northwest through the Iron Gate region where it gains a jet effect, then continues to Belgrade.
[5] The same study showed that Košava usually lasts for two or three days, one-day events being very rare.
Košava wind blows when there is a high air pressure (an anticyclone) over Eastern Europe and/or west Asia and a low pressure (a cyclone) over the middle and/or western Mediterranean region.
[7] Košava's occurrence can be successfully forecast using the across-mountain mean sea level pressure and potential temperature differences.
