Wind rose is defined as "any one class of diagrams designed to show the distribution of wind direction experienced at a given location over a considerable period."
- Wind rose shows the prevailing direction of wind.
- It consists of a circle from which eight or sixteen lines emerge
- Each line signifies a specific direction
- Length of a line is proportional to frequency of wind from that direction
- Frequency of calm conditions is entered in the center
- Wind roses are constructed from data obtained over a particular month, season or year
- Wind direction refers to the direction FROM which wind is blowing
- Sometimes, instead of wind speed, the parameters of precipitation, smoke, sulphur dioxide, smok, hydrocarbons, etc are attached to wid direction. These diagrams are known as POLLUTION ROSES.
