air pockets
Turbulence-causing voids
Air pockets are regions where air is trapped or isolated—a bubble in liquid, a void in solid material, or an enclosed space in clothing that provides insulation.
In aviation, an air pocket is a sudden downdraft that causes a plane to drop unexpectedly: We hit some air pockets over the mountains.
