Variations of wind speed and direction with altitude is known as
A) supercells.
B) convection.
C) wind shear.
D) convergence.

Question

Quizplus · Accepted Answer

Wind shear refers to the variations of wind speed and direction with altitude, which can cause instability and turbulence in the atmosphere. Supercells refer to severe thunderstorms with rotating updrafts, while convection refers to the process of heat transferring within a fluid (such as the atmosphere) which can cause vertical motion of air. Convergence refers to the coming together of two air masses, which can also cause instability and weather disturbances.
