Hole punch clouds, also known as "fallstreak holes," are fascinating and beautiful atmospheric phenomena. They occur when supercooled water droplets in a cloud are disrupted, often by an aircraft passing through, leading to a circular gap in the cloud. This creates a striking visual effect, often surrounded by wispy cloud formations.
This slideshow of photos shows an array of hole punch clouds taken in different places. I love looking at these, and would be very glad to see one in real life sometime.
They remind me of UFOs, especially in the photos where there's a white circular puff in the center of the hole punch. Hole punch clouds are relatively rare, so count yourself lucky if you've seen one.
