WebWhat Is Wind and How Is It Measured? Wind is the movement of air from high pressure to low pressure. It is caused by the differences in air pressure due to variations in temperature, elevation, and other factors. Wind speed is measured using an instrument called an anemometer, which records the velocity of the wind. WebA wind blowing from the south has a wind direction of 180°. A wind blowing from the west has a wind direction of 270°. In general, wind directions are measured in units from 0° to 360°, but can alternatively be expressed from -180° to 180°. Direction Name: Winds are named for the direction from which they come, followed by the suffix -erly. did fleetwood mac perform at woodstock
