Wind causes erosion and transports dust, spray, and other pollution. The effect of the wind varies according to the situation. For mechanical damage and loads, the driving force is windpower. Windpower = windspeed x windspeed. So, when windspeed is 1/4,  windpower is  1/4 x 1/4 = 1/16. Windpower is what you feel when you try and stand up in a strong wind. Clearly, even a small reduction in windspeed is enough to cause a dramatic reduction in windpower. With erosion the effect is even more pronounced as dust transport is proportional to wind speed cubed, or windspeed x windspeed x windspeed. A windbreak (also called a wind fence or wind shelter) can reduce windspeeds by over 50% of the incoming windspeed over large areas, and over 80% over localized areas.
