Which of the following is a major factor in the formation of a tornado?
A. High pressure
B. Subsidence
C. Weak wind shear
D. Strong wind shear
Answer: Option D
Solution (By JKSSB Mock Tests)
Tornadoes form in environments with strong wind shear, where there is a change in wind speed and direction with altitude, leading to rotating updrafts (mesocyclones) within thunderstorms.
Explanation:
The saturated adiabatic lapse rate (about 0.6°C per 100m) is less than the dry adiabatic lapse rate (about 1°C per 100m). This is because when air is saturated, condensation releases latent heat, which partially offsets the cooling.
Explanation:
The tropical regions receive direct (high-angle) solar radiation, concentrating sunlight over a small area and providing high energy, resulting in warm temperatures year-round.
