RSE “Kazhydromet” begins a new column on the meteorological instruments. Today's post is dedicated the Flyuger vil'da.
the First design of this type of anemometer was described in 1450 by Leon Alberti (Italy). Later in the nineteenth century G. I. Wildon was developed the modern model of wind vane and is used on the weather stations to the present day.
In meteorology there are two kinds of vane with light and heavy boards. The first is intended for measuring the wind speed from 1 to 20 m/sthe second measures the speed from 4 to 40 m/s.
According to modern sources, Flyreg vilda is used in meteorology from 1872 to the present time to measure the direction and speed of wind. Unlike the majority of instruments at weather stations, which are mounted at a height of 2 m from the ground, weather vane measured wind speed at the height of 10-12 m
an Ordinary weather vane still can be seen on the roofs of houses. Somewhere he performs a decorative function, and some of its direct applications – indicates the wind direction.
