Strong wind shear is typically associated with the dynamics of the jetstream, particularly at the core where wind speeds are significantly higher. The jetstream is a fast-flowing ribbon of air at high altitudes, and the area characterized by exceptionally high speeds can create notable variations in wind speed and direction over relatively short distances.

When wind speeds on the low-pressure side of the jetstream core exceed 110 knots, there is a strong likelihood of encountering wind shear. This is due to the dramatic contrast between the high-speed jetstream winds and the surrounding slower-moving air. Such conditions can lead to turbulence and significant changes in wind direction and speed in a very localized area, which is what defines wind shear.

Understanding this relationship is crucial for pilots and meteorologists, as wind shear can impact aircraft performance and safety during takeoff, landing, and in-flight maneuvers. Therefore, recognizing that the most pronounced wind shear occurs on the low-pressure side of a rapidly moving jetstream helps in anticipating and mitigating potential hazards in aviation.
