For METAR wind direction, the reference north is which?

Explanation:
The wind direction in METAR uses true north as the reference. In METAR, the wind is reported as the direction from which it blows, measured in degrees from true north (not magnetic). Using true north provides a consistent meteorological frame worldwide, since magnetic variation changes by location and over time. Magnetic north or magnetic bearing would introduce inconsistencies, and while geographic north is essentially the same as true north, meteorological reporting convention uses the term true north.
