Where can wind shear occur?

Wind shear can occur at all altitudes and in all directions due to various atmospheric conditions. This phenomenon is characterized by a sudden change in wind speed or direction, which can happen in multiple scenarios. For example, it can take place at high altitudes due to jet streams or around thunderstorms, where strong winds can shift rapidly.

Additionally, wind shear is frequently encountered near the surface during takeoff and landing phases, particularly when passing through temperature inversions or in the vicinity of obstacles like buildings and hills that can disrupt airflow. This versatility in occurrence emphasizes the importance of pilots being aware of and prepared for wind shear regardless of their altitude or weather conditions. This is why the understanding of wind shear is critical for flight safety, as it can impact aircraft performance and control.
