• Wind Shear in the Atmospheric Boundary Layer:
• Definition: The term wind shear describes the variation in wind speed and/or direction with height above the ground surface across the Earth's atmospheric boundary layer.
• Cause: Friction between moving air and ground surface topography, vegetation, and buildings slows surface winds, creating a steep vertical velocity gradient that increases with altitude up to hub height.
• Conclusion: Wind shear (Option 1).

Correct option: (1) Wind shear
