how is wind rose related to it?
It is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. It shows the frequency of winds blowing from particular directions.

A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Presented in a polar coordinate grid, the wind rose shows the frequency of winds blowing from particular directions. 
most of the u.s. is situated in which zone of prevailing surface winds Northern temperate zone how is nature affected because of this prevailing winds? Insects are swept along by the prevailing winds, while birds follow their own course. In the Great Plains, wind erosion of agricultural land is mainly driven by the prevailing wind. Because of this, wind barrier strips have been developed to minimize this type of erosion. does it cause impact on trades? Yes - the trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere. The trade winds act as the steering flow for tropical cyclones that form over world's oceans, guiding their path westward.

Prevailing winds [SEP] Wind rose
A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Presented in a polar coordinate grid, the wind rose shows the frequency of winds blowing from particular directions. The length of each spoke around the circle is related to the proportion of the time that the wind blows from each direction. Each concentric circle represents a different proportion, increasing outwards from zero at the center. A wind rose plot may contain additional information, in that each spoke is broken down into color-coded bands that show wind direction ranges.
