Košava (wind)

Košava (pronounced [kɔ̌ʃaʋa]) is a cold, very squally southeastern wind found in Serbia and some nearby countries. 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. It can spread as far north as Hungary and as far south as Niš.[1]

In the winter, it can cause temperatures to drop to around -30 °C. In the summer, it is cool and dusty. It varies diurnally, and is strongest between 5:00 and 10:00 in the morning. Košava is usually caused by a low pressure zone over the Adriatic Sea and a corresponding high pressure zone in southern Russia.[1]

The name is also used traditionally in northwestern Bulgaria to mean a southeastern or eastern wind.[2][3] There exists the saying: "When košava blows, the Nišava freezes".[4]

Speed and occurrence of the Košava wind have declined in the period 1949-2010.[5] The same study showed that Košava usually lasts for 2 or 3 days, 1-day events being very rare.
