Wind speed pattern in Nigeria (a case study of some coastal and inland areas)

J.A. Oyewole, T.O. Aro


In this study, wind speeds were analysed using the daily wind data obtained from Nigeria Meteorological Agency, Oshodi Lagos at the height of 10m at the different stations during the period of 2000-2010. Weibull , lognormal and normal probability density functions were employed. It was found that the daily mean wind speed groups and percentage frequency of occurrence in brackets in the inland locations (Jos, Kano, and Ilorin) and in the coastal locations (Lagos, and Port Harcourt) ranged from (13-18) ms-1 (70.6%), (8-12)ms-1 (84.4%), (45)ms-1 (67%) and (8-12)ms-1 75.8% to (4-7)ms-1 97% of the observations respectively. Weibull shape parameters K ranged from 3.07 to 3.82. While the scale parameter C ranged from 9.91 to 15.07ms-1 for Kano; K ranged from 2.75 to 4.04 while C ranged from 12.75 to 17.44ms-1 for Jos; K ranged from 2.61 to 2.76 while C ranged from 10.58 to 10.79ms-1 for Lagos; K ranged from 1.95 to 1.98 while C ranged from 6.10 to 6.35ms-1 for Port Harcourt; and K ranged from 3.10 -5.60 while C ranged from 3.80 to 6.00ms-1 for Ilorin.
