What does wind shear involve?

Wind shear refers specifically to the variation in speed and direction of the wind at different altitudes or over short distances in the atmosphere. This phenomenon can have significant implications for aviation, especially during takeoff and landing phases, where abrupt changes in wind speed and direction can affect an aircraft's performance and stability.

While other factors like temperature, humidity, and cloud formation can influence weather conditions, they do not define wind shear. The essence of wind shear lies in the shifts in wind velocity and its directional changes, which can create challenges for pilots and necessitate careful attention and management during flight operations. Understanding this concept is crucial for safety and effective navigation in aviation.
