1. Newton's Second Law: F = ma, f = force, m = mass of the air parcel, a = acceleration. This law of Newton can be applied to air by treating it as a fluid, which applied to air, compares air acceleration to force, which includes pressure gradients, gravity, and friction within the air. Using that with the high pressure around the low pressure in a tornado, it accelerates air into the center and creates an inflow. But while the air is mostly inviscid, the friction at the ground is very viscid, which slows the wind and disrupts the circular motion, this causes it to accelerate toward the low pressure center.
2: Pressure Gradients: The force in a tornado comes from the horizontal pressure gradients coming from the air moving from the high pressure area into the low pressure center. As the pressure difference increases, the force increases, explained by Newton's Second Law, as the Pressure gradient increases, the force increases, and results in higher acceleration, in this case tornadoes have very steep pressure gradients. So the air molecules move faster and result in a tighter and stronger vortex.
3: Convergence: As the air accelerates inward into the low pressure center, it converges from all directions. When the air accumulates near the center, it goes upward, which stretches the vortex, become narrower, and spin faster. This is known as a strong updraft. The upward motion intensifies the tornado by stretching the rotating column of air.
4: Vorticity: Because the convergence forces air upwards. The air column is stretched vertically. This stretching causes an increase in rotation (vorticity) over time.
5: Conservation of angular momentum: When the air parcels move towards the low pressure center, the conservation of angular momentum requires the rotation to speed up. The angular momentum formula equation explains that if the radius decreases, the velocity increases as well.
