Because wind direction is important for alot of things such as sailing,aviation and wind farms. I mean if the wind turbines couldn't face into the wind they'd be very ineffecient. Also if you have wildfires than its life or death if you know the wind currents.
wind vane
It is not read , it calculates which direction the wind is blowing at
The direction you are facing has no bearing on the direction the wind is blowing. It can come from any where.
A wind vane measure wind direction. It doesn't measure wind speed, it tells which direction the wind is coming from and which direction it is currently blowing.
Indicates the direction of the wind. It is use to know where is the wind going. Wind vanes are used to tell the direction the wind is coming from.

Depends on what you mean by observation. There are instruments that measure wind velocity, There are wind socks that show if the wind is blowing and what direction.
The reference point is FROM that direction AND that is the way it is blowing.
It shows the direction where the wind is coming from. Like the North, South, East or west. Weather vane or wind vane does not measure anything, it just shows the direction the wind is out of, a wind monitor measures the force the wind is blowing, in mph or kph. Wind vanes indicate wind direction and when this information is recorded, describes the direction FROM which the wind is blowing. Wind vanes measure the direction in which the wind is blowing. anemometer The direction the wind is blowing from. So it measures wind direction.
When we measure wind direction, we go by the direction it is blowing out of. If we have 315. 360-45 = 315 which on a compass is NW. This wind we are talking about here is out of the NW. It would then be blowing SE.
Typically wind direction and wind speed. However if you use the technical definition of velocity (speed and direction) then wind velocity and it's acceleration are most important. For example, it's great to know that the wind is blowing at 5 knots NE, but if it's steadily increasing, and veering to the south that's important to know too.
The direction from which the wind is mainly blowing from.
sand dunes important in tornadoes as when the tornadoes come the high pressure wind take it to the direction where the wind is blowing
A wind vane tells you which direction the wind is blowing and an anemometer tells you the speed the wind is blowing.
FROM the North Eastern direction.
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.
