Turbulent air movements occur in the layer of the atmosphere adjacent to the earth's surface, and such layer is known as the atmospheric boundary layer. Such movements are affected by the roughness of the earth's surface, and its height can be up to one kilometer. Various objects on the ground, such as buildings, row trees, forests, etc., in terms of the impact on the air movement itself, are viewed as elements of roughness. The wind speed in different areas varies, so in parts above sea level it increases significantly with increasing altitude, while in areas of higher terrain roughness such an increase is much slower. The windbreaks are barriers that reduce speed and redirect wind flow. They are usually made of trees and shrubs, and they can also be protective fences. Reducing the wind speed behind the windbreak changes the environmental conditions and microclimate in the protected area. The main structure of windbreaks consists of height, density, number of rows, composition of species, length, orientation, and continuity. These factors determine the effectiveness of windbreaks in reducing wind speed and changing the microclimate. Numerous methods can be used to protect the soil from the effects of wind erosion, from making the soil surface more resistant to wind action to setting up barriers. The efficiency of windbreaks in order to reduce wind speed can be modeled by various simulation methods.
