Where can wind shear occur?

Wind shear can occur at any altitude, making it a critical factor for pilots operating unmanned aircraft. This phenomenon involves a sudden change in wind speed or direction over a short distance, and it can take place in various atmospheric layers due to different weather conditions.

For instance, wind shear can be present during takeoff and landing phases, especially near the ground where turbulence can be significant due to obstacles, or it can be encountered at higher altitudes in the presence of jet streams or thunderstorm activity. Understanding wind shear is essential for ensuring safe flight operations, as it can impact the stability and performance of the aircraft regardless of altitude.
