Flow of air can be described using several synonyms, including air current, wind, breeze, gust, draft, and airstream. An air current refers to the movement of air along a particular path or direction and can be either natural or man-made. A breeze, on the other hand, is a gentle wind that may have a cooling effect. A gust is short-lived, sudden burst of wind that can cause a temporary change in the environment. A draft is a steady flow of air that moves through an enclosed space, such as a room. Airstream refers to the continuous flow of air that moves along a particular path. Overall, these synonyms help to describe different aspects of the flow of air.
