Fallstreak Hole: Το εντυπωσιακό φαινόμενο πάνω από την Αττική (Βίντεο)

Rare cloud formation spotted in west Michigan

A fallstreak hole (also known as a cavum, hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. The holes are caused by supercooled water in the clouds suddenly evaporating or freezing, and may be triggered by passing aircraft. Such clouds are not unique to any one geographic area and have been photographed from many places. Read more about this here- https://en.wikipedia.org
