Wind Shear is defined as a sudden change of wind velocity and/or direction. Wind Shear may be vertical or horizontal, or a mixture of both.
ICAO defines the vertical and horizontal components of Wind Shear as follows:
🟢 Vertical wind shear is defined as change of horizontal wind direction and/or speed with height, as would be determined by means of two or more anemometers mounted at different heights on a single mast.
🟢 Horizontal wind shear is defined as change of horizontal wind direction and/or speed with horizontal distance, as would be determined by two or more anemometers mounted at the same height along a runway.
