Wind direction is the direction which the wind comes from.
A North wind blows FROM the North TO the South. When you hear someone say North wind, East wind, South wind, or West wind, they are referring to the direction the wind is blowing FROM.
If the wind is coming from the north, you would indicate the wind direction as "north." This convention is based on the direction from which the wind is originating, not where it is heading.
FROM the North Eastern direction.
Wind direction is described in terms of the compass direction,or the angle relative to North, from which the wind is arriving.
If the wind is from the north, the wind vane will point to the south. The wind vane is weighted so that the wind can swing it in the direction that it is going.
north west
it points into the wind. wind direction is referenced so that if you face the direction the metiorologist says the wind is, it will hit you in the face. ie.. 10kts @ 040 (or north east), if you turn to the north east, the wind will be blowing in your face.
I used a wind vane to see what direction was the wind blowing to
That is true.
Rain gauage is used in measuring relative humidity.
