What is true about wind shear?

Wind shear refers to a change in wind speed and/or direction with altitude. It is an important phenomenon in aviation, especially because it can affect aircraft performance during takeoff, landing, and in-flight maneuvers.

The statement that wind shear occurs near thunderstorms is accurate and highlights one of the most common situations where pilots need to be vigilant. Thunderstorms are notorious for creating significant vertical and horizontal wind changes as the storm develops, which can lead to turbulence and sudden changes in airspeed or altitude as an aircraft flies through the affected area. This phenomenon may cause hazardous conditions for aircraft, making it crucial for pilots to be aware of potential wind shear when flying in or near thunderstorms.

If considered in the context of the other options, wind shear can occur at various times of the year, and its presence is not limited to winter; therefore stating that it only occurs in winter is misleading. Additionally, while radar can be an effective tool for detecting certain weather conditions associated with wind shear, such as thunderstorms, it does not directly measure wind shear itself. Rather, it identifies severe weather patterns where wind shear is likely to occur. Lastly, wind shear is characterized by inconsistency in its strength and direction; it can vary significantly depending on environmental conditions, meaning it is
