National water and climate centre (NCRS), USA explained that a wind rose enables the understanding of the direction and distribution of wind speed at a specific location.Ī wind rose is represented as a series of concentric circles with spokes where the length of each spoke is linked with the frequency of wind blowing from a certain direction indicated by that particular spoke. Moreover, these parameters influence processes such as evaporation rates, surface water mixing which further affect the water quality and the water level. Wind speed and direction are both important for evaluating weather conditions and climate and predicting them. In 2010, Fondriest staff defined wind speed as the speed of air blowing over a particular location in a specified time, and wind direction as an indicator of the direction from where the wind begins to generate. This can be achieved by drawing or constructing a wind rose diagram. Thus, it is important to determine the necessary wind data of a target area to estimate a suitable location for installing windmills and wind turbines. The average of annual measurements is taken for placing in the locations where maximum wind speed can be received. The Danish wind industry association mentioned that determining wind direction helps in setting up wind turbines and windmills in the direction of the wind and to a suited elevation. Windmills are used at industry and household level to conserve power, whereas wind turbines are used in wind farms and wind energy industries.
Wind energy is considered as a renewable source of energy which can be used to operate windmills and wind turbines at locations where the intensity and speed of wind energy are strong enough for them to function properly. Wind Rose is a representation of data in such a way that it helps us to understand wind direction, speed and frequency in a circular format.
