To measure the wind direction, traditionally, we used a weather vane, which would point to the direction the wind was...

WebWind is the horizontal motion of the air; usually due to pressure differences. Wind can come from all directions. Wind vanes measure the direction from which wind is blowing on a 360˚ compass by tens. Wind speed is measured by a spinning device called an anemometer. Wind traveling at 1 mph is also traveling at 0.4 m/s or 0.87 knots. WebWind measurement. Winds come in all directions and speeds. They are measured by their directions and speeds. Depending on the cause of the winds, they can blow in many directions. Some good examples of wind direction are the Easterly winds, which blow from east to west, and westerly winds that blow from west to east.
