摘要：The wind speed characteristics of Juja, (altitude of 1416 m above sea level; 10 10’ S, 370 7’ E), Kenyawas analysed at heights of 10 m and 30 m. The wind speed averages at 10 m and 30 m were found to be 2.54 m/s and3.04 m/s, respectively. The wind shear exponents and roughness parameters were analysed and found to be 0.1652 and0.0374 respectively. Weibull scale and shape parameters were obtained using Weibull-fit, Regression and theMaximum Likelihood. Wind speed modelling was done using the Weibull and Rayleigh probability distributionfunctions. Power densities for different methods were calculated. Results obtained from Juja site were compared withresults acquired from Naivasha, St. Xavier site which is at an altitude of 2,086 m; 0° 43' 0" S, 36° 26' 0" E. The meanwind power densities for Juja (10 m and 30 m) and Naivasha (10 m) were 12.68 W/m², 20.65 W/m² and 39.95 W/m² byWeibull model and 14.51 W/m², 22.43 W/m² and 28.63 W/m² by Rayleigh model respectively. The Weibull-fit andMaximum Likelihood fitted best Juja site and Naivasha site respectively.
