Abstract Hourly wind data of Quetta airport (Samungli) for 1984 and 1985 are analysed on the basis of speed frequency curves, diurnal variations and of the speed duration curves. In this paper, we conclude that the speed frequency curves give more reliable information as compared to speed duration curves, from the view-point of the wind energy utility, i.e. the estimation of the average power output. However, wind-tunnel testing is required to observe wind flow over the topography of Quetta and to estimate the longterm wind power. We conclude, in addition that the location of data collection as well as the accuracy of input wind data becomes critical to wind resource assessment; which required computer simulation of wind data over at least a period of 10 years by numerical analysis and mathematical models.
