Illustration of the anemometer invented by Dr. John Thomas Romney Robinson, of Armagh Observatory, in 1846. This is a device for measuring wind speed, and is a common weather station instrument. By counting the number of rotations of the cups over a set period of time one can deduce the wind speed. | |
