Wind Vanes
Wind vanes: the most reliable weather service!
Most people have always used wind vanes to determine the oncoming weather – instead of those weather services that aren’t area specific! Now you can use a wind vane too to determine the weather: simply align the pointer with the compass points below it to determine the name of a blowing wind, and check up what kind of weather usually accompanies that wind. Most people know this information off by heart because the wind is the most important factor in the climate.
How does the pointer actually work?
The pointer is carefully balanced so that it spins with a changing wind and always comes to rest in the source direction of that wind. It rotates on the weathervane axis and settles through the careful calibration of the balance of the design.
Can you get other pointers besides roosters?
Traditionally roosters and arrows are used to point out the source direction of a wind, but nowadays you can actually get any shape or design as long as it is well balanced before manufacturing.
