प्रश्न

Advertisements
उत्तर
- Distribution of air pressure and winds on the surface of the earth.
- Upper air circulation is caused by factors controlling global weather and the inflow of different air masses and jet streams. The movement of jet streams, like the Westerly Jet and the Tropical Easterly Jet, significantly impacts weather patterns over India, especially during the monsoon.
- The inflow of western cyclones is generally known as disturbances during the winter season and tropical depressions during the southwest monsoon period in India, creating weather conditions favourable for rainfall.
