Not all contemporary people install vanes in their yards. Maybe if they knew more about wind vane uses, they would install them more often. So how does a weather vane work and what is it for?

Wind vane: what does it measure?

A wind vane is a device that can determine the direction of the air stream at the moment. Most often, it is fixed on the roofs of houses. It is made of thin metal or plastic so that it could rotate when even the slightest wind blows. Sometimes it is combined with an electronic device called anemometer to measure not only the air stream direction but also its speed. Its function seems very simple. But not all people know that it can be installed for diverse purposes and in various places.

What are the wind vane uses?

Weather vane uses are numerous. The tool is employed in many fields, but it is good only when the wind blows.

  • The primary purpose of weather vane is weather monitoring. For those people who live near water or in stormy areas, these tools are essential.
  • The device often serves as a decorative element.
  • One can also meet the tool in golf fields. They serve to define airstream direction and therefore make necessary adjustments for a fair game.
  • Gardeners often use weathercock to get rid of moles, shrews, and other similar pests. For this purpose, both windmill and wind vane are good as long as they have a similar principle of functioning. Vibrations transmitted to the ground from the rotation of the propeller, frighten off rodents, and they leave the garden.
  • The device may be useful in the period of a thunderstorm. Lightning strikes the most elevated objects at the Earth’s surface. Such an object may be a rooftop or a vane located in the garden. It is logical that rightly grounded metal pole with a vane on it may save your roof and house from fire and perform the role of lightning conductor.
  • One of the weather vane uses consists of measuring the direction of the wind in the airports. Pilots need to know the direction of the air stream to adjust their aircraft control system. However, often the simplified version of the device is used. It is called windsock or wind sleeve. The principle of work is the same, but instead of wind rose, tissue in the form of a cone is used. It is faster for pilots of taking off aircraft to glance on fluttering bright piece of fabric than to follow the movements of a wind rose. You can compare vane and wind sleeve on the photo below.

  • The tool mentioned above may also be employed on sailing boats as additional means of orientation in the open sea. If something happens to onboard electronics, sailors may use compass and weather vane to find out if the redirection of a boat is possible.
  • Meteorological stations use vanes separately or in combinations with an anemometer to measure not only airstream direction but also air flow speed. Besides, there can be used in contemporary and more sophisticated devices. They are digital and more sensitive devices.

  • Step 3. Put paper figures into the slots in the straw. Use glue to fix them properly. Accordingly, the triangle will point the on-air stream direction.
  • Step 4. Take a paper cup and fill it with tiny rocks. It must be heavy and therefore steady. Firmly put a lid on it.
