2. Weather vane - Wikipedia

   en.wikipedia.org/wiki/Weather_vane

   A wind vane, weather vane, or weathercock is an instrument used for showing the direction of the wind. It is typically used as an architectural ornament to the highest point of a building. The word vane comes from the Old English word fana, meaning "flag". A cockerel is a traditional figure used as a vane placed on top of the cardinal directions.

3. Windsock - Wikipedia

   en.wikipedia.org/wiki/Windsock

   Wind tees are shaped like an airplane so that they match with the heading of an aircraft ready to take off and land. Wind tetrahedrons always have their pointy ends pointing to the wind. Wind tees and tetrahedrons can swing freely and align themselves with the wind direction, but neither measures the wind speed, unlike a windsock.

4. Self-steering gear - Wikipedia

   en.wikipedia.org/wiki/Self-steering_gear

   Another version of wind vane self steering on sail boats is known as the vertical axis vane and usually, because of the inferior steering force output compared to servo pendulum devices it makes use of a trim tab hung off the rudder to control the course of the boat. The vane spins at right angles to the ground and can lock to the trim tab in ...

5. Wind direction - Wikipedia

   en.wikipedia.org/wiki/Wind_direction

   Consequently, a wind blowing from the north has a wind direction referred to as 0° (360°); a wind blowing from the east has a wind direction referred to as 90°, etc. Weather forecasts typically give the direction of the wind along with its speed, for example a "northerly wind at 15 km/h" is a wind blowing from the north at a speed of 15 km/h ...

6. Anemoscope - Wikipedia

   en.wikipedia.org/wiki/Anemoscope

   An anemoscope is a device designed to show the direction of the wind, or to indicate a change of wind direction . The name is usually applied to an apparatus consisting of a wind vane above, connecting to a building below by some kind of coupling, and with a dial or index with pointers to show the direction and changes of the wind.

7. Weather station - Wikipedia

   en.wikipedia.org/wiki/Weather_station

   Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time. Wind sock for measuring general wind speed and wind direction; Wind vane, also called a weather vane or a weathercock: it shows which way the wind is blowing. Evaporation pan for measuring ...

8. 'Feels like' temperature: What does it really mean and how ...

   www.aol.com/feels-temperature-does-really-mean...

   For example, in a scenario where the actual temperature is 10 degrees but the "feels like" temperature is -5 degrees, what that really means is that the wind chill is making it feel as if the air ...

9. Yaw system - Wikipedia

   en.wikipedia.org/wiki/Yaw_system

   In the event of skew winds the "wind pressure" on the swept area causes a yawing moment around the tower axis (z-axis) which orients the rotor. [1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
