Result
Your answer: —  Â·  Correct: B
Explanation

The Bora is a cold and dry north-easterly katabatic wind that blows from the mountains toward the eastern shore of the Adriatic Sea [3]. It is caused by a significant pressure difference between the cold continental air over the interior plateaus (such as the Dinaric Alps) and the warmer Mediterranean air over the sea [2]. This phenomenon is most frequent and intense during winter when high-pressure systems sit over snow-covered mountains, forcing dense air to descend rapidly through mountain gaps. While the Mistral is a similar cold wind, it specifically affects the Rhone Valley in France [2]. The Bora is characterized by violent gusts and can reach gale-force strengths, significantly impacting visibility and maritime safety along the Dalmatian and Istrian coasts.
