Air vane

Air vanes are a valuable device that teaches us where to tell which way the wind is blowing. They’re like small arrows that indicate which way the wind is blowing. But how do they work? Let's find out! 

Air vanes are typically mounted on the roofs of buildings or on poles, so that they are exposed to the wind. When a gust of wind comes along, the air vane rotates and faces into the gust, and turns the machine as it does so. That tells us the wind is from the north, the south, the east or the west. If we glance at the air vane, we know what to expect of wind. 

The science behind air vanes and their role in meteorology

Weather is the study of the weather. Air vanes are useful to meteorologists as the make weather forecasts. By knowing which way the wind is blowing, meteorologists can produce better forecasts about rain, clouds and changes in temperature. This is critical information for farmers, pilots and anyone who needs to know what the weather will be.
