except that, in events that measure wind velocity, the following shall be satisfied: The average velocity (that is, the sum of the wind velocities, as measured for each individual event, divided by the number of such events) shall not ...
Wind is moving air. When the sun warmsthe ground, air near the ground gets warmer. The warm air is lighter and moves up. Coolerair moves down and fills in the place where thewarm air was. This movement of air makeswind. Measuring Wind Wind ...

Anemometer, device for measuring the speed of airflow in the atmosphere, in wind tunnels, and in other gas-flow applications. Most widely used for wind-speed measurements is the revolving-cup electric anemometer, in which the revolving cups drive an elec
Biomass sex allocation of Alnus firma, a wind-pollinated self-incompatible monoecious tree species, was directly measured at the inflorescence (prezygotic) stage. Sex allocation ratio at the fruit stage was estimated from the number of female inflorescences, percent fruit production, and the mean ...
Windstorm, a wind that is strong enough to cause at least light damage to trees and buildings and may or may not be accompanied by precipitation. Wind speeds during a windstorm typically exceed 55 km (34 miles) per hour. Wind damage can be attributed to
The flight of separated straws is thought to affect the cleaning wind of a combine harvester. To comprehend the turbulent flow characteristics of the cleaning wind and its passage through the grains, the cleaning wind velocity is measured by particle image velocimetry and laser Doppler velocimetry. ...
