A weather vane is the primitive version of an anemometer.
First, a Weather Vane needs to be on the highest spot on the building. That way you can get the most accurate reading. The Vane needs to have a pointer that has a wider end so that the wind can push against it. Beneath the arrow is the fixed directional markers, N, E, S, and W.
There are so many awesome designs for a Weather Vane too.
There is an old John Wayne movie where he throws his hat onto the roof and it catches on the weather vane. It was very common in the olden days to have one on roofs. They counted on knowing the wind direction to as they depended on the weather for their livelihood. Now people use them to decorate the house with a flat version of a weather vane. Some still put it on their roof for their own fun.
How does a weather vane work?
With the flat end of the pointer, the wind catches and spins it around until the wind cannot push anymore. The arrow will be pointing to the direction the wind is coming from. That is why when you read the direction of the wind it says, “From North”. When we put the Wind Speed and direction in our weather info, that is what it means.
Did you know that the World’s Largest Weather Vane is a Douglas DC-3 airplane that sits on a pedestal? It is in front of the Yukon Transportation Museum in Canada. If you would like to know more about it, go to atlasobscura.com (https://www.atlasobscura.com/places/worlds-largest-weathervane-dc-3)
Meteorologists weather vane
Meteorologists use the general Weather Vane’s along with an anemometer. It is a very simple way to get the direction and speed.
Airport Weather Vane
A lot of airports use a Wind Sock. Windsocks catch the wind which makes it point to the direction it is going. Depending on how taut the sock is, is a general indicator of speed but is not exact.
