Answer:
Wind Shear is the difference in direction and speed of the wind in the atmosphere within a specific distance.
Explanation:
Eddies are generated when winds goes over a mountain creating vertical shear on the side that is sheltered from it, that creates air pockets causing atmospheric turbulence know as "rotors".
The change of direction and wind speed with altitude variation is called Vertical wind shear.
The change in wind speed together with a change in lateral position at a certain altitude is called Horizontal wind shear.
One scenario is a mountain with down-bursts and micro-bursts creating ice crystal plumes clouds that could warn pilots of wind shear, allowing then to avoid accidents.
