Turbulence

Posted on: August 14th, 2008
You  have probably experienced how hailstorms or thunderstorms in particular, are associated with frequent gusts of wind which both change speed and direction.
In areas with a very uneven terrain surface, and behind obstacles such as buildings there is similarly created a lot of turbulence, with very irregular wind flows, often in whirls or vortexes in the neighbourhood.
Turbulence decreases the possibility of using the energy in the wind effectively for a wind turbine. It also imposes more tear and wear on the wind turbine, as explained in the section on fatigue loads. Towers for wind turbines are usually made tall enough to avoid turbulence from the wind close to ground level.
