This wind speed database gives estimates of the annual mean wind speed throughout the UK. The data uses an air flow model to estimate the effect of topography on wind speed. There is no allowance for the effect of local winds such as sea, mountain or valley breezes. The model uses a 1 kilometre square resolution and does not take account of topography on a small scale, or local surface roughness (such as tall crops, stone walls or trees), which may have a considerable effect on the wind speed. The data should be used as a guide only and should be followed by on-site measurements for a proper assessment. Each value stored in the database is the estimated average for a 1 kilometre square area, at either 10 metres, 25 metres or 45 metres above ground level (agl). The database uses the Ordnance Survey grid system for Great Britain and the grid system of the Ordnance Survey of Northern Ireland. This database is being maintained for reference and archive purposes only, and is no longer being updated. Users should note that this database uses historic information, and not live, up-to-date data.
