A fallstreak hole (also known as a cavum, [1] hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds.

Jan 22, 2025 · But jets can cause a different type of cloud feature, called hole-punch clouds, aka fallstreak holes. They look like abrupt clearings in an altocumulus cloud layer, often circular patches of...

A fallstreak hole (also known as a "hole punch cloud") is a large circular or elliptical gap that can appear in cirrocumulus or altocumulus clouds. How do they form? High to mid level clouds, such as altocumulus, are often composed of tiny water droplets that are much colder than freezing, but have yet to freeze.

Fallstreak holes, also known as hole punch clouds, are a “supercool” phenomenon, where large circular or elliptical gaps appear in mid- to high-level cirrocumulus or altocumulus clouds.

UFO theorists are right to an extent: Hole-punch clouds, also called fallstreak clouds, are caused by flying objects, but those objects are easily identifiable: airplanes. Hole-punch clouds occur within two types of common cloud layers: 1) cirrocumulus or 2) altocumulus clouds .

Mar 5, 2025 · Fallstreak holes are defined as large circular or oval-shaped openings that form in cirrocumulus or altocumulus clouds when supercooled water is turned into ice crystals, causing surrounding water droplets to evaporate. This occurrence is predominantly the result of aircraft passing through a cloud.

Feb 25, 2024 · Cavum, also called hole-punch clouds and fallstreak holes, look so odd that people sometimes argue they are signatures of flying saucers or other unidentified anomalous phenomena. Seen from below, they can look like a large circle or ellipse has been cut neatly from the clouds, with feathery wisps left in the middle of the hole.

May 31, 2024 · Fallstreak holes are huge circular or elliptical gaps that can appear in cirrocumulus or altocumulus clouds. When seen from below, they can look like a large cavity that has been neatly carved...

Dec 29, 2024 · Cavums are also known as hole-punch clouds or fallstreak holes. These features often appear as large, circular gaps in an otherwise unbroken sheet of altocumulus or cirrocumulus clouds. What is a cavum?

Definition: A circular gap cloud feature better known as a fallstreak hole or hole punch cloud Description & Characteristics. The ‘cavum’ cloud feature can be found amongst three cloud types: cirrocumulus, altocumulus, and stratocumulus.

Feb 11, 2025 · A supercool phenomenon known as a hole punch cloud was spotted in Georgia. This is how they form.

Dec 11, 2003 · During the early afternoon of December 11, 2003, a strange and unusual cloud formation occurred over the Mobile, AL area. The name..."Hole Punch Clouds". Has it happened before? Yes. A quick internet search quickly reveals a few strikingly similar past photos that were taken in south Florida, the Carolinas and even Australia and Canada.

Jan 28, 2013 · These rare cloud formations, called "hole-punch clouds", develop in altocumulus cloud layers and are often the result of airplanes passing through the layer of clouds. So, how does this...

Feb 27, 2024 · Cavum clouds, also called hole-punch clouds and fallstreak holes, look so odd that people sometimes argue they are signatures of flying saucers or other unidentified anomalous phenomena. Seen from below, they can look like a large circle or ellipse has been cut neatly from the clouds, with feathery wisps left in the middle of the hole.

Feb 7, 2021 · Fallstreak holes, also known as hole-punch clouds, are the result of cold air temperatures and atmospheric instability. Viewed from below, it can appear as if part of the cloud is falling out of the sky.

Jul 6, 2024 · The process seems easy enough, but what could introduce these necessary particles (cloud condensation nuclei) to create this process and why does it look like a hole? The answer is airplanes!

Oct 22, 2024 · Also known as a hole punch cloud, the phenomenon shows large circular or elliptical gaps in mid- to high-level cirrocumulus or altocumulus clouds, according to NOAA’s National Environmental Satellite, Data, and Information Service, or NESDIS.

Jan 14, 2025 · It is called a hole punch cloud or a fallstreak cloud. It forms because there is lots of water all across the sky in the form of clouds. At high elevations, it's all below freezing but it actually has not frozen into ice yet.

A fallstreak hole (also known as a cavum, hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large circular or elliptical gap that can appear in cirrocumulus or altocumulus clouds. It forms when part of the cloud layer forms ice crystals that are large enough to fall as a 'fallstreak'.

A fallstreak hole (also known as a cavum, hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds.
