Wind shielded areas can also be considered areas of low wind speed or momentum. These can simply be found using an isosurface of a low momentum magnitude, as shown below. The wind shielded areas aren't found until you look near the area of the winds exiting the city. This is possibly due to a simulation error, or possibly because the portion of the city near the wind "entry" point is the first contact point of the wind. It may require alot of obstructions before the wind is sufficiently slown down enough for any visible difference.
