Wind shear is a sudden change in wind speed and/or direction over a short distance, and it can occur at any level in the atmosphere. However, it is particularly prevalent at low altitudes and within frontal zones. Frontal zones, which are regions where two air masses meet, commonly experience significant wind shear due to the differences in temperature and pressure between the colliding air masses.

Additionally, low-level wind shear is often encountered during takeoff and landing phases of flight, making it crucial for pilots to be aware of these conditions. While wind shear can indeed occur in mountainous regions or during thunderstorms, it is not limited to just those scenarios, thus highlighting its presence at various altitudes and in various weather conditions. Hence, understanding that wind shear can manifest in multiple environments, especially at lower altitudes, helps in recognizing its significance for flying safety and operational procedures.
