Low-Level Wind Shear

Low level wind shear is characterized by small-scale, intense downdrafts which, on reaching the surface, spread outward from the downflow centre. This causes the presence of both vertical and horizontal wind shear that can be extremely hazardous to aircraft, particularly during the approach to landing and in the takeoff phases. On takeoff, this aircraft may encounter a headwind, followed by a downdraft, and tailwind in a short period of time.
