The strength of the wind depends on both the local wind distribution and the height of the building – the taller the building, the greater the impact of wind on the building and plants. The wind acts directly on the plants mechanically, breaking their flowers, leaves, branches, as well as the flow caused by the wind dries the plants, reducing the amount of moisture in them.
