Correct Answer:
B. Western Disturbances
During winter, Punjab, Pakistan, is primarily affected by Western Disturbances. These are extratropical storm systems originating in the Mediterranean Sea, which travel eastward, bringing crucial winter rainfall and occasional snowfall to northern Pakistan and parts of India. These disturbances are vital for the region's winter crops and water reservoirs.
- Monsoon winds occur during summer.
- Sea Breeze is a localized coastal phenomenon.
- Tropical Cyclones are rare in winter and primarily affect coastal areas, not inland Punjab.
Therefore, Western Disturbances are the correct climatic influence.
