The ERA-Interim reanalysis wind based on the distance-weighted average remapping for studying\nthe wind circulation in Nigeria is presented. The wind flow using this atmospheric model simulation\nis studied for identification of grid-tie electrification opportunities in different wind locations.\nA 10-year reanalysis wind speed components at a surface level of the planetary layer at 0.25 Ã?â??\n0.25 spatial resolution is obtained and remapped into a new horizontal wind field at a grid resolution\nof 0.125 Ã?â?? 0.125 covering longitudinal and latitudinal directions of 3.0 - 15.0E and 15.0 -\n3.0N, respectively. Using the distance-weighted average technique, the remapped wind field at a\nnew grid resolution of 0.125 Ã?â?? 0.125 is compared at different terrain elevations and approximated\nclose to the actual wind field of the same resolution. To determine the suitability of the\nprevailing wind for small-scale energy conversion, the magnitude of wind flow across the remapped\nwind field is studied for a 10-year period. Analysis shows that northern regions of Nigeria\nhave a fair wind potential for a stand-alone application based on the wind flow originated at Gulf\nof Guinea as well as Chad and Niger. Furthermore, hourly surface wind speed observations from\n18 synoptic stations in Nigeria are obtained and compared with the bilinear interpolated wind\nstations. The reanalysis wind reflects the surface wind observations and proves that the prevailing\nwind in Nigeria is higher than the reanalysis wind projection obtained from gridded data at resolution\nof 0.125 Ã?â?? 0.125. The sectorwise wind directions at each synoptic stations for a period of\n10 years are presented.
