remains constant
slowly becomes zero
The angular speed of a whirlwind in a Tornado towards the centre remains constant.
In a whirlwind in a tornado, the air from nearby regions gets concentrated in a small space thereby decreasing the value of its moment of inertia considerably. Since, Iω = constant, so due to decrease in moment of inertia of the air, its angular speed increases to a high value.
