Previous Year Question
Which one of the following pairs is not correctly matched?
Fohn — Alps Mountain
Bora — Poland
Mistral — Rhone Plateau
Khamsin — Egypt
Correct Answer: B
Detailed Solution
The Foehn is a warm and dry downslope wind whose name was originally associated with the European Alps. Moist air rises on the windward slope of a mountain, cools and may produce precipitation; after crossing the mountain, it descends on the leeward side and becomes warmer and drier through adiabatic compression.
The Bora is not a wind of Poland. It is a cold, dry and strong local wind associated mainly with the eastern and northern coastal regions of the Adriatic Sea, particularly around Croatia and Slovenia. It develops when cold continental air descends rapidly from elevated terrain towards the Adriatic coast. Hence, Bora–Poland is incorrectly matched.
The Mistral is a very strong, cold and dry north or north-westerly wind of southern France. Its influence is particularly strong around the Rhône Valley and Rhône Delta. In the question, it is associated with the Rhône region.
The Khamsin is a hot, dry and dust-laden local wind of Egypt. It generally blows towards Egypt from the Sahara and continental interior and can be particularly prominent during the spring season.
