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.
2024年4月18日 · Specifically, a wind vane measures where the wind is blowing. For example, if a modern wind vane says “east,” the wind is going in an easterly direction. Not only can wind vanes help you determine the direction of the wind in the moment, but they can also help measure weather patterns over time.
weathervane 在英語-中文（繁體）詞典中的翻譯. noun [ C ] uk / ˈweð.ə.veɪn / us / ˈweð.ɚ.veɪn / Add to word list. a metal object, usually with a part shaped like an arrow, that is put on top of a high building and turns to show which way the wind is blowing from. 風標，風向標. (weathervane在劍橋英語-中文（繁體）詞典的翻譯 © Cambridge University Press) weathervane的 例句.
基本信息. 中文名： 風向標. 英文名： wind vane. 用途： 測定風來向的設備. 適用領域： 氣象、化工、礦區、農業等. 構造： 風標 、風輪、尾翼、動桿等. 外形： 尾翼、平衡錘、指向桿、轉動軸. 簡介. 風向標. 各種測風儀器中用以指示風向的最主要的部件。 分為頭部、水平桿和尾翼3部分。 風速和風向是分別利用磁感風速杯和風向標來量度。 磁感風速杯通常有三個對稱風杯，固定於垂直軸上，令每個風杯的直徑面都是垂直。 由於風杯凹面比凸面承受較大的風力，風杯輪便會隨風轉動，觀測員可從風杯轉動的速度來確定風速。 至於風向，則由風向標顯示。 風向標基本上是一個不對稱形狀的物體，重心點固定於垂直軸上。 當風吹過，對空氣流動產生較大阻力的一端便會順風轉動，顯示風向。
A wind vane (also known as a weathervane) is an instrument that tells you the wind direction. Specifically, a wind vane lets you know what direction the wind is coming from. In other words, a “southwest” reading on a wind vane means that the wind is originating southwest of your location, and heading in a northeast direction.
