What is the main contribution of wind shear in mesocyclone formation?
Answer and explanation
Correct answer: It can tilt horizontal rotation into vertical rotation
Wind shear produces changes in wind speed or direction with height, creating horizontal vorticity or rolling motion. A strong thunderstorm updraft can tilt this horizontal rotation into the vertical and stretch it. The resulting organized vertical rotation is a key part of mesocyclone development in a supercell.
