Vertical wind shear In the study of vertical wind shear, the formula

is sometimes used, where P is a variable that depends on the terrain and structures near ground level. In Montreal, the average daytime value for P with north winds over 29 mi/hr was determined to be 0.13. If a 32 mi/hr north wind is measured 20 feet above the ground, approximate the average wind shear (see Exercise) between 20 feet and 200 feet.

Vertical wind shear Vertical wind shear occurs when wind speed varies at different heights above the ground. Wind shear is of great importance to pilots during takeoffs and landings. If the wind speed is v1 at height h1 and v2 at height h2, then the average wind shear s is given by the slope formula

If the wind speed at ground level is 22 mi/hr and s has been determined to be 0.07, find the wind speed 185 feet above the ground.
