Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

In a whirl wind, the air from nearby region from nearby region gets concentrated in a small space thereby decreasing the value of moment of inertia considerably. Since, Iω = constant, due to decrease in moment of inertia, the angular speed becomes quite high.
In a tornado,the moment of inertia of air will go on decreasing as the air moves towards the center. This will be accompanied by an increase in angular velocity such that angular momentum is conserved.
