Hole Punch Cloud

The video explains the phenomenon of hole punch clouds, which occur when airplanes fly through altocumulus or cirrocumulus clouds, causing supercooled water droplets to freeze and form ice crystals. This process creates a visible hole or canal in the cloud layer. The video provides examples of these clouds observed in various locations and discusses the impact of air traffic on their formation. It highlights how these clouds can be tracked by satellites and emphasizes the environmental implications of increased air traffic.
