side of a mountain. The stronger the wind, the greater the downward pressure and turbulence become. Figure 12-16. Turbulence in mountainous regions. Due to the effect terrain has on the wind in valleys or canyons, downdrafts can be severe ... helpful for a pilot unfamiliar with a mountainous area to get a checkout with a mountain qualified flight instructor. Low-Level Wind Shear Wind shear is a sudden, drastic change in wind speed and/or direction over a very small area…
