Often the cosmetic accent atop the heyday of a barn roof , weather vane add rustic appealingness while service as a peter for nurseryman care to determine the malarky ’s steering . Oriented and marked according to the fundamental instruction of north , due south , east and west , the vane has one swiveling limb that rotates grant to the wind ’s origin . The pointed pointer of the pivot arm always points into the twist , revealing the counselling from which the wind originates . Thus , a vane that points to the " N " prove that the wind is blowing ( starting ) from the north and move to the south .
Step 1
Look at the vane and note if there are any fundamental direction mark . There may only be one , which in all likelihood will be the letter " N " for north , or it might also have the other markers–“S " for Dixie , " E " for Orient and " W " for Cicily Isabel Fairfield . These markers are stationary and point to the fundamental directions .
Step 2
suffer still for 10 to 30 seconds and watch for movement of the vane ’s wind arrow . This moveable and swiveling weapon of the weathervane traditionally look like an arrow with a pointed arrowhead and seat Phoebe or plume . Once seen , note which end of the wind pointer is the pointed peak and which is the seat from your vantage gunpoint .
Step 3
take the direction of the flatus pointer on the weathervane . The pointed tip of the wind pointer points into the wind . Based on the directional marker on the vane , deduct where the wind pointer points according to the four cardinal directions . If the jazz pointer is point outwards between the " tocopherol " and " S " guiding markers , the wind is coming from the sou'-east . In other words , the current of air originates from the SE and blend in to the northwest .
Step 4
get into that a quickly rotating or spinning wind pointer on a weather vane indicates variable twist , trigger-happy eddies or changing air current . A resting wind arrow means no wind or a very lightheaded wind that is too light for the current of air arrow to indicate .
Tip
Weathervanes only reveal the commission from which the wind originates , not its speed or intensity . Some weathervanes , as they age , may not be as sensory to idle words as metallic element parts corrode or wear down . Examine wind vane once every one to two years to grease the swivel ray of the movable vane indicator . mod weathervanes may have an wind gage incorporate , which does reveal wind hurrying .
Warning
Always use attention when access and working around weather vane on roof flush or other gamy structures or precipitously pitched locations .
