Which of the following is a major factor in the formation of the polar jet stream?
A. Pressure gradient force
B. All of the above
C. Temperature contrast between polar and tropical air
D. Coriolis force
Answer: Option B
Solution (By JKExamLibrary)
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:
Distance from Earth's core has no effect on climate. India's climate is influenced by latitude, altitude, distance from sea, Himalayas, and monsoon winds.
Explanation:
Supercell thunderstorms are characterized by a rotating updraft (mesocyclone) and form in environments with strong wind shear (changing wind speed and direction with height), which allows the storm to sustain itself for hours.
Explanation:
Monsoon deficiency refers to a situation where the rainfall received during the monsoon season is below the long-term average, leading to drought conditions in some regions.
