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.
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.
The Earth is a "closed system" which means that the amount of rocks, carbon, metals, nitrogen, water and oxygen on earth remains constant.
So it is essential that "biogeochemical cycles renew these materials" as they move through the Earth's subsystems.
<u>Explanation</u>:
The Earth's only source of extra-planetary energy is the Solar radiations received by Earth.
The biogeochemical cycles on the planet are responsible for processing the same old rocks, metals, carbon, nitrogen, oxygen, water, and other abiotic substances on Earth in order to naturally renew them and make them available for reuse.
No naturally occurring element on Earth is newly produced. It is only renewed through biogeochemical processes.
