An invisible but universal phenomena, huge wingtip vortices can be seen in the twisting fog as this airplane lands in Zurich, Switzerland. Wingtip vortices are strong spirals of air that are created when high pressure air below the wing spills up around the top of the wing, a relatively lower air pressure space, making a small horizontal tornado.

A Kinetic Mind by Elizabeth Rudge introduces the kinetic sculptures of artist Anthony Howe. The sculptures are visually interesting patterns when still, but are mesmerizing when the wind powers their spinning, rotating, reflecting, interweaving… 

Watch A Cloud Light, above, or check out Octo, or maybe this standing Vlast-O-Spline, though this Bob-sythe is rather incredible… what’s your favorite?

I suddenly have the urge to go blow across the top of a bottle. This is Aeolus, an Acoustic Wind Pavilion, and I have no doubt that we would stand within it for quite a while… great sound. It reminded me immediately of England’s Singing Ringing Tree, as well as the sound of Tibetan Singing Bowls


This amazing art project goes along with my latest YouTube episode about gusty science: What Is Wind?

Luke Jerram is a colorblind artist based in the UK. Aeolus is a sonic creation that blends acoustic physics, inspirations from classical civilizations, and visual adventure. The arch is a large Aeolian harp, an ancient instrument that uses the wind’s vibration on strings to send a frequency down a long metal tube. 


A listener in the center of the arch experiences sounds transmitted from a field of taut strings and naturally harmonic open tubes. In addition, the angle of light transmitted through the polished pipes creates an altered listening environment. The experience can change by the minute or hour depending on wind conditions.

The tightened strings vibrate due to something called the von Karman vortex street effect, where the vortex created behind a string causes it to vibrate. It’s similar to what happens when a car antenna begins to sing in the wind.

You can see a photo gallery here, and listen to interviews and sound samples here.

A true feat of beauty and science.
