Abstract:

This communication attempts to analyze Karachi coastal area (Paradise Point 24.84º E, 66.77º N)) for an understanding of underlying probability distribution. It has been found that at this site the annual wind speed at a height of 30 meters remains very close to 7 m/s whereas at a height of 61 meters the wind speed reaches to 9 m/s. Moreover, the wind mostly remains directed towards southwest. Furthermore, the annual average wind speed follows Weibull distribution and the annual average wind speed goes on increasing with the passage of time. Maximum energy together with the energy density for different values of the wind mill blade diameters is also calculated. Our analysis shows that the wind speed is increasing as a consequence of global climate change. Though the global climate change has created many threats to the humanity by influencing the local urban microclimate but the positive aspect of this finding is that the increase in wind speed will increase the feasibility and economic viability of the construction of wind farms near Karachi coast and offshore. Of course these calculations will be useful for urban and energy planners.
