Which of the following is a major factor in the formation of the polar jet stream?
A. Temperature contrast between polar and tropical air
B. All of the above
C. Coriolis force
D. Pressure gradient force
Answer: Option B
Solution (By JKSSB Mock Tests)
The polar jet stream forms due to the strong temperature contrast between polar air and tropical air, creating a steep pressure gradient and strong winds, which are then deflected by the Coriolis force.
Explanation:
India is affected by multiple jet streams: the polar jet and subtropical jet in winter influence Western Disturbances, and the tropical easterly jet in summer affects the monsoon.
Explanation:
A monsoon is a seasonal change in wind direction, typically from land to sea in winter and sea to land in summer, bringing heavy rainfall to the land.
