Wind shear was the shear force, or difference in speed or direction of wind, between two points in an atmosphere.
In 2151, wind shear on the surface of Archer IV prevented Shuttlepod 2 from landing and recovering a landing party. (ENT: "Strange New World")
In 2368, William T. Riker described the wind shear on a moon of Mab-Bu VI as "incredible" when attempting to land with the shuttlecraft Campbell. (TNG: "Power Play")
