Correct answer: A. The Shamal winds

  1. Step 1: Analyze regional wind climatology: In Arabic, 'shamal' translates literally to 'north'.
  2. Step 2: The Shamal is a persistent northwesterly wind system that blows across Iraq and the Persian Gulf into eastern and central Saudi Arabia, whipping up blinding sandstorms.
Answer
The Shamal winds.
Why not the others: 'The Khamsin' is a hot, dry, dust-bearing wind blowing north across Egypt from the Sahara; 'The Sirocco' blows across the Mediterranean into southern Europe; 'The Harmattan' blows across West Africa.
