A ‘Hole Punch’ Cloud Makes a Rare Appearance Over Southern California
Science| | By Margo Gothelf
In order for a rare hole punch cloud to form, the clouds must be “vertically thin,” explained NBC Los Angeles. “A plane must fly through, which creates a big temperature difference. The temperatures beneath the wings of a C-130 airplane, for example, are 14 degrees warmer than the surrounding environment,” NBC Los Angeles wrote. “This temperature difference and propeller motion creates a dry punch of air falling from the sky, evaporating the clouds beneath.”
According to the Weather Channel, the clouds can also take shape “when a few ice crystals ‘spontaneously’ form within the supercooled cloud and then ‘take over.’” Many Southern California residents posted photos of the uncommon hole punch cloud formation to social media. Many users were looking to acquire some information regarding the one-of-a-kind formation. “Hey, what kind of cloud formation is this??” one user wrote. Check out some of the shared images below!
