The wind characteristics of greatest interest are generally speed, direction and gusts. These parameters are examined through their representations as time-frequency plots. Such plots provide an excellent means for illustrating the changing nature of the spectral characteristics or features of time-varying parameters. Of particular interest here is the use of such plots to identify and track fundamental properties of the wind and associate them with different weather conditions. Several algorithms for generating time-frequency displays are evaluated and compared. Different ways of displaying the time-frequency plots are also illustrated. The results appear to provide an excellent means of assessing wind characteristics that can meet the needs of many applications.
