"Pappa! Come here! Why is the rain doing that?!"
Our towers are spaced close to each other, maybe the tower is 50 m wide and the distance wall-to-wall to the next tower is just 10 m or even less, so the passage between two towers can have pretty high wind speeds.
Now it's raining and windy, so first of all we can see the general vertical rain outside the window, nothing weird with that. But occasionally there will be a powerful burst of wind between the towers and it will bring with it a white spray of water sucked in from the other side of the passage. So you kind of see these waves of white spray through the air, it's quite a unique view.
