my question is would a line of wind turbines have a comparable effect to a wind break in reducing wind velocity
If that's to what the OP was referring, it's a whole different scale than what came to my mind. I was thinking of the kind we had to cut down on soil erosion in dry times on the farm or minimize snow drifting in winter due to surface winds. Hurricane taming wouldn't work on the same principle (I don't think) because of the sheer vertical area they cover and hurricanes are more susceptible to interference a higher altitudes where the "rim" speed is lower.theOrange said:If it is possible to use wind turbines to reduce the power of a hurricane

Way back in the 1920s, Cypress seedlings were handed out for free by the Department of Agriculture so farmers could plant wind breaks. These formed good wind break hedges that only required to be trimmed once each year. Unfortunately, farmers are busy and kept putting off the inconvenient job of trimming the top of 12 foot high hedges, so the hedges became lines of trees, now between 4 and 8 foot diameter at the base, 100 foot high, dropping big old branches on buildings and equipment. The area under the trees is now bare of other vegetation and clear of low branches, which makes an efficient wind tunnel for wind obstructed by the middle part of the tree.theOrange said:You may be right, either way trees are probably more cost effective.
Yes - one can use tall trees, but at some distance from buildings and equipment. One would need lower shrubs, but also rows of trees.Baluncore said:Where trees are used as wind breaks, the species selected should remain low, such as a shrub, or have foliage that fills the area between the trees as close to the ground as possible.
Yes, wind turbines can be used as wind breaks in open farm land as they are designed to withstand strong winds and can create a barrier that reduces wind speeds and turbulence.
Wind turbines help protect crops from wind damage by reducing the speed and force of the wind, which can prevent crops from being blown over or damaged. They also create a sheltered microclimate that can protect crops from extreme temperatures.
There can be some negative impacts of using wind turbines as wind breaks, such as casting shadows on crops, creating noise pollution, and disrupting local wildlife. However, these impacts can be mitigated through careful placement and design of the wind turbines.
Vertical axis wind turbines (VAWTs) are often considered the most suitable type of wind turbine for use as wind breaks in open farm land. This is because they have a lower profile and can be placed closer to crops without casting shadows or interfering with crop growth.
While trees can also act as wind breaks in open farm land, they are not always as effective as using wind turbines. Trees may not offer as much protection from wind speed and turbulence, and they also require more maintenance compared to wind turbines. Additionally, wind turbines can generate clean energy while also serving as wind breaks, making them a more sustainable option.
