Hard Geography Class 11 Level 2

Geostrophic winds are mainly related to balance between which two forces?

भू-संतुलित पवनें मुख्यतः किन दो बलों के संतुलन से संबंधित हैं?

Show answer and explanation
Correct Answer

A. दाब प्रवणता बल और कोरिऑलिस बल / Pressure gradient force and Coriolis force

Explanation

Step 1: The concept is upper air winds. Step 2: At higher levels friction is weak and pressure gradient force balances Coriolis force to form geostrophic winds. Step 3: Remember geostrophic as PGF plus Coriolis balance.

Step 1: अवधारणा ऊपरी वायुमंडलीय पवनों की है। Step 2: ऊँचाई पर घर्षण कम होता है और pressure gradient force तथा Coriolis force संतुलित होकर geostrophic wind बनाते हैं। Step 3: Geostrophic equals PGF plus Coriolis balance याद रखें।
