Original Note:
These Cavum Clouds or Hole Punch Clouds: https://www.youtube.com/watch?v=HYZNhtpajF8&t=29s Are a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. They are caused by supercooled water in the clouds suddenly evaporating or freezing, and may be triggered by passing aircraft. https://cloudappreciationsociety.org/cloud-library/cavum/ https://www.earth.com/news/cavum-clouds-nasa-captures-mysterious-holes-cloud-formation-florida/
