Question

The speed of Inner layers of whirlwind in a tornado is alarmingly high . why?

Answer 1

in a whirl wind the air from nearby region gets concentrated in a small space thereby decreasing the value of moment of inertia considerably. since,constant decrease in moment of inertia the angular speed become quite high.

Answer 2

The speed of inner layers of whirlwind in a tornado is alarmingly high because in a whirlwind the air from the surrounding areas are concentrated in a specific area increasing the speed of the winds.

• In reference to the conservation of angular momentum, the inner layers of the whirlwind or tornado have the highest wind speeds.

• In the inner layers of a whirlwind or tornado, moment of inertia of rotating air decreases and thus angular velocity increases that makes it extremely dangerous
