When you're walking around malls or parking structures, or a building corner, you'll sometimes notice areas with consistent windiness.
I was wondering what positions, angles, wind direction, pressure, temperature or other variables would be involved if one were to try to design a home or building to get this consistent windy effect.
Sometimes it can be as simple as building corners (at least apparently).
I'm currently sitting in a very consistently windy passageway of a building. Roughly speaking, the building is an L-shaped building that blocks wind on either side, but has an arched hole where you can walk through. Other areas nearby aren't windy. Maybe it's because one side is sunny and the other is not, creating a pressure gradient. On the sunny side there also seems to be a heat exchanger with fins, which could also contribute to the temperature gradient. Other factors could be a wall that "catches" the wind and funnels more air through the passageway.

What I just described is a specific example, but I'm looking to generalize the principles to potentially utilize in architecture or when looking at homes to buy that could achieve this effect with some modification. (Do architects learn this stuff? In modern architecture stuff like this seems to be under-appreciated.)
Is temperature gradients and "funnel" geometry of walls significant in creating a pressure gradient (wind)?
