Wind Speed Is Measured By An Instrument. In sailing apparent wind is the speed and direction of wind indicated by a wind instrument anemometer on a moving craft on water land or ice in undisturbed air. A fast wind may be felt on a rainy day. The wind direction is measured with wind vanes or wind socks. An electrical device records the revolutions of the.
Meteorologist Grant Gilmore explains how anemometers measure wind speedsSubscribe at. It is composed of the combined speeds and directions of the craft and wind observed by a stationary wind instrumentthe true wind. The principle is that a thin metal wire called a hot wire heated by electricity is placed in the airflow. A typical anemometry mast will have a number of anemometers devices to measure wind speed installed at different heights on the mast and one or two wind vanes devices to measure wind direction. These will be connected to a data logger at the base of a mast via screened cables. Professional anemometers generally measure air movement with cups mounted on horizontal spikes that are fastened to a center shaft.
