Question

Define atmospheric wind shear, and explain how the existence of wind shear creates eddies and air pockets that cause atmospheric turbulence and clarify the differences between horizontal and vertical wind shear, and the eddies generated by each.

Describe one scenario of specific atmospheric conditions that would result in the generation of wind shear and turbulence, and any potential visual signs that may exist to serve as a warning to pilots of the potential for encountering turbulence for this scenario.



Give your take on the relevance and importance of the above concept from your own perspective.

Answer 1

Wind Shear is the difference in direction and speed of the wind in the atmosphere within a specific distance.

Step-by-step 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.
