Which of the following is a major factor in the formation of a tornado?
A. High pressure
B. Weak wind shear
C. Subsidence
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:
London is prone to advection fog (also known as sea fog) when warm, moist air from the Atlantic moves over the cooler landmass, cooling to its dew point and forming fog.
Explanation:
The ITCZ is also known as the doldrums because the converging winds create calm conditions with little to no wind, historically making it difficult for sailing ships.
Explanation:
Wind shear is the change in wind speed and/or direction with altitude. It is an important factor in aviation and weather forecasting, especially for thunderstorm development.
