Wind shear is characterized by:

Wind shear is indeed characterized by sudden changes in wind speed and direction. This phenomenon can occur at various altitudes and is particularly significant during the takeoff and landing phases of flight. It can pose serious risks to an aircraft's stability, making it critically important for pilots and drone operators to be aware of wind shear conditions.

Sudden variations in wind speed can create turbulent air, which may lead to abrupt shifts in the aircraft's altitude or attitude, making control challenging. Understanding wind shear is essential for ensuring safety and proper handling of unmanned aircraft in varying weather conditions and environments, particularly when operating near ground level or in environments susceptible to shifting winds.
