DEFallstreak holes, also known as punch hole clouds, are captivating atmospheric phenomena that appear as circular or elliptical voids in an otherwise unbroken cloud layer. These holes form when supercooled water droplets—water that remains liquid even below freezing—suddenly freeze. This process is often triggered by the passage of an aircraft or a disturbance in the atmosphere that forces the ice to form. As the ice crystals grow, they cause the surrounding droplets to evaporate, creating a cascade effect that carves out a gap in the cloud. What remains is a momentary glimpse into the delicate balance between temperature, moisture, and the sublime chaos of our planet’s atmosphere. Because of their rarity and unusual appearance, fallstreak holes have been mistaken for or attributed to unidentified flying objects.
