When it comes to describing the movement of air, there are several terms that can be used interchangeably with "current of air". For instance, "draft" refers to a current of cool air, often one that is caused by convection or the movement of an object (like a fan). "Breeze" is another common term, but typically refers to a gentler flow of air that's usually felt outdoors. "Gust" is used to describe a sudden, powerful burst of air that might occur during a storm. And finally, "wind" refers to any moving mass of air, including everything from a light, gentle breeze to a fierce gale.
