Multiple Choice

Which of the following is NOT a wind indicator?

Understanding wind indicators means focusing on what each instrument reveals about the air moving around you. Windsocks and wind cones show wind direction in a straightforward, visual way—how the fabric sits and points indicates where the wind is coming from and, rough as it is, how strong the wind is. The tetrahedron or Wind T is another simple device that orientates with the wind to reveal direction. An anemometer is all about speed, measuring how fast the air is moving past the instrument. The barometer, by contrast, measures atmospheric pressure. It’s useful for forecasting weather changes, but it does not tell you the wind’s direction or speed, so it isn’t a wind indicator.
