Here Is Information On Weathervane

By Charles Mitchell


Most of human activities rely on weather as a key aspect. This is why having the knowledge about the prevailing weather in an area is important. Weather stations have been constructed to offer weather predictions which assist individuals in planning their events better. Very complex equipment, methods and skills are used in forecasting weather. Certain devices are used to determine the prevailing weather at the moment while weather stations predict future weather conditions. This is worth knowing about Weathervane.

For example, knowing the speed of and direction of wind is possible using wind socks and weather vanes. A wind vane, otherwise called weathercock or weather vane is useful in identifying weather direction. It may be used for decorative reasons apart from telling wind direction. This is achieved by installing it at the pinnacle of a construction like a building.

In fact, even though vanes are partly functional, they are generally used for decorative purposes. When used for decorative purposes, vanes usually features the traditional cockerel design with points of the compass indicated by letters attached to it. Other motifs that are used commonly include horses, arrows, and ships. Not all vanes are made with pointers. The head of the vane is usually designed so that it points in the direction the wind is blowing from.

Although vanes were created hundreds of years ago, they still find use currently. The first text that talks about this device as a wind-observing fan dates back to the 139 BCE in China. Away from references from texts, a real wind vane was developed and installed on top of the tower of winds in Greek which ages back to 50 BCE.

People have gone ahead to design some ridiculously large wind vanes to win Guinness World Records. At the moment, the Tio Pepe Sherry weather vane in Jerez, Spain holds the Guinness World Record for being the largest weather vane. Another claim has been laid to the Guinness World Record by the city of Montague in Michingan. The vane in Michigan measures 48 feet tall.

The vane found in the Whitehorse region of Yukon is another contender of the largest vane record. It was crafted from a Douglas DC-3 CF-CPY installed atop a revolving support. It is found in Yukon Transportation Museum adjacent to the Whitehorse International Airport. It is depended upon by pilots to identify wind direction prior to landing or takeoff.

The vane in Whitehorse, despite being huge, is effective. It can only rotate at a 5 knot wind speed. There are numerous tourists attracted to the vane. Furthermore, the local residents like passing near it and viewing its huge size.

From the text above, it is clear that vanes can be made from any material and with any design. They can also be made to any size one wishes them to be. For the wind vane to be able to respond to weak winds, it must be designed, positioned, and anchored well. This becomes even more important when the device is very big.
