      Wind shear is a gradient, which means it exhibits a specific change of wind velocity over a given distance. Wind shear can be horizontal, vertical, or both. If the wind direction changes as well as the wind speed, the actual wind shear will be greater than the wind speed shear alone. The most critical wind shears for pilots occur over horizontal distances of 1 mile or less and over vertical distances of 1,000 feet or less.
