风向标是测定风的来向的仪器。一般安装在四周空旷、离地约10米高的杆子上。在风压作用下，风标箭头指风的来向。一般會分作頭部、水平桿和尾翼三個部分。风向标最早的书面记载出现在中国西汉时期的《淮南子》，时称侯風扇[1]。公元前50年古雅典建设的风之塔顶则安装了风向标保留至今[2]。欧洲一些鸡型的风向标又称作风信鸡。 風向標 同時可測風速的風向標 Remove ads 西方屋顶常见的鸡型风向标（風信雞）風向計 Remove ads [1]Needham, Joseph; Ling, Wang, Science and Civilisation in China: Mathematics and the Sciences of the Heavens and the Earth 3, Cambridge University Press: 478, 1959 [2]Noble, Joseph V.; Price, Derek J. de Solla.
