When air flows around an object there exists a critical velocity where vortices begin to form on the leeward side. These vortices consist of a series of alternating low pressure zones which then cause the object to vibrate at a resonant frequency. Structures such as poles, chimneys, suspension bridges, electrical transmission lines, and even tall buildings can become quite sensitive to these effects. This phenomenon is known as a Karman vortex street.
