Upward Air Current

An upward air current, also known as an updraft, is a vertical movement of air that occurs when warm air rises and is replaced by cooler air. Upward air currents are commonly found in areas of convective activity, such as thunderstorms, and can be a hazard to aviation due to the potential for turbulence and icing. However, they can also be beneficial to aircraft, as they can provide lift and increase altitude without the need for additional engine power.
