The aerodynamics of a windsock are complex but basically they involve compression. The compression is very small but it is enough to force the sock up and out. When wind enters the sock at the large end it is forced down the tapered tube. As the tube gets smaller, the pressure and speed of the wind is increased.

How do wind socks work for kids?

The aerodynamics of a windsock are complex but basically they involve compression. The compression is very small but it is enough to force the sock up and out. When wind enters the sock at the large end it is forced down the tapered tube. As the tube gets smaller, the pressure and speed of the wind is increased.

Function. Wind direction is the opposite of the direction in which the windsock is pointing, so a windsock pointing due north indicates a southerly wind. Wind speed is indicated by the windsock’s angle relative to the mounting pole; in low winds, the windsock droops; in high winds it flies horizontally.
