| 2. Indian Monsoon System |
B. Local Winds |
| 3. The northern plain 'Loo' |
C. Permanent Winds |
Answer & Solution
Correct option is A
Explanation:
1. Trade Winds & Westerlies → C. Permanent Winds
→ Permanent winds flow reliably across the globe throughout the year in fixed directions.
→ The Trade Winds and Westerlies are driven by permanent latitudinal atmospheric pressure belts.
2. Indian Monsoon System → A. Seasonal Winds
→ Seasonal winds periodically reverse their flow direction in response to seasonal temperature variations.
→ The Indian Monsoon is a classic example of large-scale seasonal wind shifts caused by differential heating of land and sea.
3. The northern plain 'Loo' → B. Local Winds
→ Local winds blow only during specific periods over limited geographic regions.
→ The hot, dry Loo wind blows during summer days across the northern plains of India.
Information Booster:
→ Permanent winds are also called planetary winds because they maintain general atmospheric circulation cells.
→ The Coriolis force, caused by the Earth's rotation, deflects winds to the right in the Northern Hemisphere.
→ Sea breeze and land breeze are smaller, daily local wind patterns common along coastal zones.
→ The Loo can cause severe heat strokes, making it a critical local weather phenomenon in northern India.
→ Dynamic shifts in pressure belts cause the shifting of global wind systems throughout the year.
