Answers
Wind direction is reported by the direction from which it originates. For example, a northerly wind blows from the north to the south.[1] Wind direction is usually reported in cardinal directions or in azimuth degrees. Wind direction is measured in degrees clockwise from due north. Consequently, a wind blowing from the north has a wind direction of 0° (360°); a wind blowing from the east has a wind direction of 90°; a wind blowing from the south has a wind direction of 180°; and 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°.
"NW 12 mph" in a weather forecast indicates a wind coming from the northwest (toward the southeast) having a wind speed of 12 miles per hour.
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).
