Hole Punch Clouds Form Over Middle Georgia
MACON, Georgia (41NBC/WMGT) – A super cool weather phenomenon happened this morning over Bibb County! Luckily, we were able to see it occur on our Jeff Smith Automotive 41 Skyview Camera in Macon from the Coliseum Medical Centers.
See the large, circular gap of blue sky surrounded by clouds? That is called a hole-punch cloud or fallstreak.
The clouds were given the name “hole punch” because jets can punch a hole into the clouds.
Aircrafts passing through altocumulus or cirrocumulus cloud layers can trigger the formation of the phenomenon. When an aircraft passes through these cloud layers, the air in the cloud rapidly expands and cools. As it cools, the water droplets also cool and some freeze, becoming ice crystals. As the ice crystals form, the surrounding areas of the cloud evaporate. Heavier ice crystals can fall, forming a cloud streak (hence the name fallstreak).
