| Two of them, a wind vane for measuring direction and an anemometer for measuring speed, sit atop a telescoping pole. |
| Scientists and pilots measure the speed of the wind with an instrument called an anemometer. |
| This value will give you the approximate angular velocity of the anemometer. |
| He became interested in wind speed and invented a pressure-tube anemometer, the first device to measure both the velocity and direction of wind. |
| Study of turbulence in the upper layers of the atmosphere using an anemometer attached to a stratospheric balloon. |
| The measurement of wind speeds is usually done using a cup anemometer, such as the one in the picture to the left. |
