Question

There are three primary conditions needed to form an ordinary thunderstorm. Which condition is required to form a severe thunderstorm, but is not required to form an ordinary thunderstorm?

1) vertical wind shear
2) lifting mechanism
3) warm, humid air
4) unstable atmosphere

Answer 1

Vertical wind shear is the condition required to form a severe thunderstorm, but not required for an ordinary thunderstorm.

Step-by-step explanation:

The primary condition required to form a severe thunderstorm, but not required for an ordinary thunderstorm, is vertical wind shear.

Vertical wind shear refers to the change in wind speed and direction with height in the atmosphere. It is necessary for severe thunderstorms because it creates a rotating column of air, which can lead to the formation of tornadoes.
