Marine turbulence and wind shear on a boat installed wind generator
Wind sheer describes the interference between the fast moving upper air and the slow moving air close to the ground and the resulting decrease in average wind speed as one gets closer to the ground.
Turbulence is caused by the wind passing over obstructions such as moored boats, trees and buildings. Both wind sheer and turbulence diminish with height and can be overcome simply by putting the turbine sufficiently high above them. It is therefore essential that the windcharger should be located in an area as free as possible from disturbed wind flow. Bear in mind that downwind obstructions can be as detrimental to performance as upwind obstructions.
