Two vanes? What if they're pointed at each other?

Actually, even though they're three stories up, and separated by only
30 feet, I've already seen them briefly point at each other.

The wind is capricious, for sure.

You see that kind of thing a lot when you are racing sailboats. Sheer lines
between air that is moving / not moving or moving in two different
directions are common. Also, when there is verticle movement, the wind will
flow inward to or outward from a small area. Life is good when you are on
the right side of one of those wind lines. It sucks when you are standing
still while your competitor is moving along at 5 or 6 knots just a short
distance away.

I assume the same thing can be found at airports, but it may be less obvious
except when it messes up your landing. (back to aviation content)
