Weather vanes, in some form or another, have been around for about two thousand years. They are also known as wind vanes, which is a more accurate title for these gadgets, since there purpose is to show wind direction only, not to tell us anything other than that about the current weather. In fact the word “vane” is an old Anglo-Saxon word “fane” that means “flag”. These days probably most weather vanes you see on suburban homes are used purely as decoration.
Another name for weather vanes is weathercock. In fact, one of the original versions of a weather vane was a cock design containing letters for each point on the compass. These were often seen at farms on the top of the farmhouse or the barn. Knowing the wind direction can help farmers know if a storm is near since wind direction is a key part of forecasting the weather. Wind brings the weather with it.
How does a weather vane work? They are normally made up of an asymmetrically shaped object mounted on an axis, like a rooster, with an equal amount of weight on each side of that axis. However, the surface area of the object must be larger on one side. For instance, the tail of the rooster would have more surface area than the head. Quite often, an arrow will be mounted below the main object to act as a pointer. When the wind blows, the side with the larger surface area blows away the incoming wind and the arrow points into the wind to show the direction from which the wind is coming.
Most weather vanes will have marks beneath the pointer to indicate north, south, east, and west. It is important that the vane be installed so that each directional indicator mark is pointed in the right direction. It also must be mounted in a spot where the wind will not be blocked by trees or structures. It helps to first fix the weather vane to a pole and then mount this entire apparatus to the roof.
Some more sophisticated wind vanes are connected to a remote pre-calibrated dial so that the wind direction can be read without actually going outside and observing the direction in which the pointer is facing.

What is the modern mean for the prediction of weather?
Weather forecasting has come a long way with the advent of modern technology. Where once there were handheld instruments with dials and tubes, now there are radar systems and satellites assisting meteorologists in predicting the weather. Some older instruments are still in use with the more advanced tools, giving meteorologists as complete a picture of incoming weather systems as possible.
