What unit is used for wind direction?
In general, wind directions are measured in units from 0° to 360°, but can alternatively be expressed from -180° to 180°. Winds are named for the direction from which they come, followed by the suffix -erly. For example, winds from the north are called “northerly winds” (north + -erly).
What is weather instrument tells wind direction?
A wind vane (also known as a weathervane) is an instrument that tells you the wind direction. Specifically, a wind vane lets you know what direction the wind is coming from. In other words, a “southwest” reading on a wind vane means that the wind is originating southwest of your location, and heading in a northeast direction.
