摘要：The knowledge of the prevailing wind characteristics (speed and direction) in an environment is vital for proper farmstead planning, as it influences the appropriate location and orientation of structures in view of taking optimal advantage of the wind and minimizing the damaging effects. In North-Central Nigeria, the prevailing wind in many locations is generally unknown. This has created a shortfall in the planning, design, layout and orientation of farmsteads. It is therefore imperative to provide information about the wind speeds and directions in this region. This study made attempts to develop wind rosettes of various locations in North Central Nigeria, with a view of establishing the prevailing wind directions and speeds in the region. Wind data for 18 years (1994-2012) for Makurdi, Abuja, Ilorin, Minna, Jos and Lokoja were obtained from Nigeria Meteorological Agency, Abuja. The data were analyzed and the wind rosettes for these locations were developed using WRPLOT View. The Wind rosettes show that the predominant wind directions are; west, west, southwest, south, east, and south respectively for Makurdi, Abuja, Ilorin, Minna, Jos and Lokoja. Average wind speeds from these locations are also respectively 6.15m/s, 6.79m/s, 7.63m/s 7.72m/s, 12.28m/s and 5.43m/s. The prevailing wind speeds in the prevailing wind directions for the locations are within the range of 6-8m/s for Makurdi and Abuja, 4-6m/s for Lokoja and Minna, 8-10m/s for Illorin, and 12-14m/s for Jos. The maximum wind speeds within the study periods were respectively 25m/s, 30m/s, 30m/s, 44m/s, 52m/s and 19m/s for Makurdi, Abuja, Ilorin, Minna, Jos and Lokoja. This information is invaluable for farmstead planning and layout in North-Central Nigeria.
