Final answer:
The statement is true; vortex stretching in a supercell leads to the concentration of rotation in a mesocyclone, an action that can result in tornado formation.
Step-by-step explanation:
The statement about supercells and mesocyclones is true. Within a supercell, the process of vortex stretching does indeed concentrate the rotation in a mesocyclone. Tornadoes, which emerge from this environment, exhibit a fascinating aspect of rotational motion in nature. A rotating column of air within the supercell shifts from a horizontal to a vertical axis, often leading to the formation of a tornado. The eye of the tornado, which is the center of rotation, experiences weaker winds due to the inverse proportional relationship between tangential velocity and the square of the radius of curvature. Additionally, phenomena such as hurricanes are affected by the Coriolis force, causing storms in the Northern Hemisphere to rotate counterclockwise and those in the Southern Hemisphere to rotate clockwise.
