About the Cover

The paper seeks to examine the spatial and the temporal variations of surface winds over Northeastern Nigeria and their potential for energy generation. Wind data for six (6) synoptic stations located in northeastern Nigeria were obtained from the Nigerian Meteorological Agency (NIMET). The stations; Nguru, Maiduguri, Potiskum, Gombe, Bauchi and Yola are well distributed across the region. Descriptive statistics - mean, standard deviation and coefficient of variation - were used in analyzing the data. In addition, inferential statistics - time series analysis and regression were also used to provide further insight into the temporal and spatial characteristics of surface wind over the study area. The study found surface wind to vary over time and space. It was also observed that the North-east trade wind plays a key role in influencing the variations of Harmattan season climatic elements especially surface wind flow; because it is the driver of the season and is controlled by the movements of the Inter Tropical Discontinuity (ITD). Latitude has also demonstrated a great deal of influence on the variations of climatic parameters in the region. Accurate documentation of surface wind characteristics over the study area help in the determining the specification of suitable wind turbines for various locations (Ref: Luka Fitto Buba, Nura Umar Kura, Dantata Danlami, John Bathrobas Dakagan. Harmattan wind and its potential for electricity generation in Northeastern Nigeria. Discovery, 2018, 54(275), 432-441).
