Locations with trees, buildings, and steep terrain topography that offer a rough surface for wind lead to high wind shear (the rate the wind decreases in speed as it nears the ground) and lower mid-level wind speeds as well as more significant turbulence close to the ground. However, Bernoulli´s Principle tells us that when air flows through a narrower space it speeds up which means that when wind funnels up over a ridgeline, hill, or through a mountain pass, it accelerates. This acceleration creates a lower wind shear and increased turbulence intensity, both of which increase the energy Wind Harvesters can extract.
