Why is wind shear turbulence particularly dangerous at low levels?

Wind shear turbulence is particularly dangerous at low levels primarily because it can lead to abrupt altitude changes, especially during crucial phases of flight such as takeoff and landing. During these times, an aircraft is generally at a lower speed and agile maneuverability is limited. Sudden changes in wind speed and direction can result in a rapid loss of lift or sudden descent, catching pilots off guard and making recovery difficult. This unpredictability can create a hazardous environment, especially when the aircraft is close to the ground and requires a delicate balance of speed and altitude control.

While other factors like unpredictability and risks of mechanical failure can be significant in their own right, the immediacy and impact of altitude changes during takeoff and landing make the consequences of wind shear turbulence at low levels particularly severe. The proximity to the ground reduces margin for error, heightening the risk of accidents in these situations.
