Wind shear refers to a change in wind speed and/or direction over a relatively short distance in the atmosphere. It can occur in both vertical and horizontal planes and is a critical factor for pilots to understand, especially during takeoff and landing phases.

The characteristic that wind shear may be associated with a wind shift or windspeed gradient is accurate because wind shear can manifest in various atmospheric conditions, not just during thunderstorms. For instance, it can occur at significant altitudes as a result of the jet stream, frontal passages, or even thermal gradients created by differing surface temperatures. Such variations in wind can create hazardous conditions for aircraft, especially during critical phases of flight.

By recognizing that wind shear can arise from wind shifts and changes in wind speed, pilots can better prepare for and respond to its potentially dangerous effects. Identifying these wind characteristics is crucial for situational awareness and effective flight management.
