Aeolian and local climate impact

Scientists have used the atmospheric model RAMS
(Regional Atmospheric Modeling System) to assess the impact
could have a large number of wind turbines on the climate of the Great
Plains. Somnath Baidya Roy from Princeton University (New
Jersey), and colleagues simulated the presence of 10000 park
giant wind turbines with 50 blades concentrated on 9300
square kilometers in northern Oklahoma. In this region,
there overnight fast wind that separates the cold damp air near the
Soil that hot and dry in altitude. But experience has established that
turbines, capturing this current cause turbulence in
their wake that cause vertical mixing of air masses.
And when warm air reaches the surface, the same type is obtained
climate impact than that produced by deforestation
large scale. For now, these results are still only
preliminary, but they underline the importance of seeking to
improve the rotors of wind turbines to reduce turbulence.
