Which climatic phenomenon, characterized by hot, dry easterly desert winds blowing from the Arabian Peninsula, frequently causes sudden temperature spikes in spring and autumn?
Answer and explanation
Correct answer: D. Sharav (Khamsin)
- Step 1: The Sharav (known in Arabic as Khamsin) is an easterly or southeasterly synoptic wind.
- Step 2: It occurs when low-pressure systems draw dry, scorching air from the desert interior, causing temperatures to rise rapidly and relative humidity to plummet below 20%.
Answer
Sharav (Khamsin).
Why not the others: The Mistral is a cold, dry northerly wind in southern France; the Sirocco blows across the central Mediterranean into Italy; the Harmattan is a dust-laden wind across West Africa.
