Weather vanes are largely decorative, but they can tell somebody the direction that the wind is coming from by the individual looking at the arrow. Get an accurate reading of wind direction with help from a science teacher and field biologist in this free video on weather.
Hi, I'm Brian, with Ericksontutoring.blogspot.com and today we're going to discuss how to read a weather vane. So, it's important to keep in mind that weather vanes are largely decorative and usually aren't able to tell you to too specific of a, of accuracy the direction of the wind, which is what they measure. So, in order to read a weather vane, the process is pretty simple. You look at your weather vane and you ask yourself, in which direction is the arrow pointing? Whichever direction the small end of the arrow, or the rooster or whatever your arrow-pointing device is, whichever direction it's pointing is the direction the wind is coming from. Pretty simple. If you want to get a little more complicated, you could stand with a compass, and point it in the same direction as the arrow is pointing, line it up and that would give you a more accurate measure in degrees of, of the wind direction. So, that's it. That's how to read a weather vane.
