Weathervane
What exactly is a weathervane?
The weathervane is more than just a pretty pointer on top of your home – it actually has a useful function. It is an instrument that is used to determine the source direction of a blowing wind so that the wind can be named. It is really easy to use: you simply line up the pointer with the compass points beneath it, and then you know what to call the wind!
Why do I want to know the name of a blowing wind?
The name of a wind can give you clues about what is going to happen to the weather. Of course this is different all across the world, but some people know the North Easterly wind to bring rain, whilst others know it to bring sunshine. It is a great way to help people predict what is going to happen to the weather, and prepare accordingly.
How do I recognize a weathervane?
Weathervanes were traditionally roosters or arrows that spun on an axis, but now you can get just about any pointer design that your heart desires. You can recognize a vane by its compass points and its location – it is always on the highest point of the building – and the fact that there is a flat design that spins with the slightest hint of a wind.
