SURFACE ROUGHNESS AND LOCAL WINDS

Abstract: By numerically simulating atmospheric flow, the impact of surface friction on winds that are canalized by a mountain is investigated. The simulations show that in the case of wind that is accelerated by orography, surface friction has a significantly stronger wind-breaking effect than if m...

Description
Summary:Abstract: By numerically simulating atmospheric flow, the impact of surface friction on winds that are canalized by a mountain is investigated. The simulations show that in the case of wind that is accelerated by orography, surface friction has a significantly stronger wind-breaking effect than if mountains have not accelerated the wind. These results are particularly encouraging for plans to change the local wind climate in Iceland by massive growing of trees.
