Fallstreak Hole in British Columbia
The Freaky Cloud Phenomenon You Need to See
Alien invasion? Nope, it's just a big ol' gaping hole in the middle of a cloud. Everyone is going insane over the fallstreak hole cloud formation that appeared twice over the past two days in British Columbia, Canada. So what on earth is this extremely rare cloud formation? Also known as a hole punch cloud, canal cloud, or skypunch, a fallstreak hole is an expansive circular gap that appears on rare occasion.
The way they form is pretty fascinating. Meteorologist Eric Elwell explains it best: "Such holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation particles. When ice crystals do form it will set off a domino effect, due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud."
