The wind in passing the summits of mountains becomes swift and dense and as it blows beyond the mountains it becomes thin and slow, like water that issues from a narrow channel into the wide sea. Notebooks of Leonardo da Vinci (1452-1519) |
Speed Up Effects: Hill Effect
A common way of siting wind turbines is to place them on hills or ridges
overlooking the surrounding landscape. In particular, it is always an advantage
to have as wide a view as possible in the prevailing wind direction in the
area. | |
You may notice that the wind in the picture starts bending some time
before it reaches the hill, because the high pressure area actually extends
quite some distance out in front of the hill. | ||
