Answer 2

If air blows north to south we use the north sign

Explanation:

• The direction of the wind is indicated by the direction from which it emerges. For example, the northerly or north wind blows from north to south.

• Wind direction is usually reported in the cardinal (or compass) direction, or degrees. As a result, the direction of the wind blowing from the north is called 0° (360°); The direction of the wind blowing from the east is called 90°, etc.

• Weather forecasts usually give the wind direction as well as its speed, for example, "north wind at 15 km/h" is the wind blowing from the north at 15 km/h.
