Wind direction changes all the time in natural winds. Although many results of fieldmeasurements have pointed out that that wind pressures on claddings have been influencedby the change of wind direction, there are a number of unclarified points about it. That isreason why the change of wind direction in natural wind has non-stationary condition. Thisreport suggests a method of analysis for estimating the unsteady wind direction, using thelocal maximum and the local minimum for the time series of wind direction in naturalwind. As a result of analysis, we understood that the fluctuation of wind velocities showeda rising tendency by the more change of wind direction.
