Overview of Fallstreak or Hole-Punch Clouds

Officially known as Cavum Clouds, Fallstreak or hole-punch clouds are circular or elliptical gaps in mid-level cloud layers caused by aircraft penetration through supercooled cloud decks.

They combine natural and anthropogenic processes, creating visually striking holes fringed by ice-crystal fallout.

Fallstreak holes primarily affect cirrocumulus and altocumulus clouds, which are composed of supercooled water droplets that can suddenly freeze or evaporate.

When a disturbance, often from a passing aircraft, initiates ice crystal formation, these droplets rapidly turn into ice and fall as ice crystals, creating the distinctive circular or elliptical hole in the cloud layer

Details

Height: Typically 10,000–25,000 feet (3,000–7,500 metres).
Look: Circular hole in altocumulus or cirrocumulus with streaks of virga descending.
Name meaning: “Fallstreak” refers to precipitation trails; “hole-punch” describes the appearance.
Rain: Occasionally light precipitation (virga) evaporating before reaching the ground.

What Do Fallstreak or Hole-Punch Clouds Look Like

Viewed from the ground, fallstreak holes appear as large circular clearings surrounded by smooth cloud edges.

Beneath each hole, streaks of ice crystals may descend in fibrous shafts. The size can reach several kilometres across, often expanding over minutes.

A History of Fallstreak or Hole-Punch Clouds

Though photographs date to the 1940s, systematic explanation came in the 2000s when satellite and aircraft studies linked the phenomenon to jet aircraft traversing supercooled clouds.

Observers once speculated that these holes might be explosions or weather modification experiments, but scientific consensus now attributes them to aircraft-induced ice nucleation.

Further Information

When an aircraft passes through a layer of supercooled water droplets, the pressure drop and particles in the exhaust trigger rapid freezing.

The newly formed ice crystals grow by the Bergeron–Findeisen process, drawing vapour from surrounding droplets and clearing the hole.

The Bergeron–Findeisen process describes how ice crystals grow within cold clouds at the expense of nearby supercooled water droplets.

It is the main mechanism behind precipitation in mixed-phase clouds, which contain both liquid and solid particles.

This process exemplifies microphysical interactions between natural and artificial triggers in cloud dynamics.

Fallstreak holes demonstrate how local disturbances can influence mesoscale cloud patterns visible even from satellites such as NASA’s MODIS instrument.

How Clouds Form

The Clouds Above
Clouds are one of the most visible and dynamic components of Earth’s atmosphere. They influence weather, climate, and even human activities, while providing a spectacular canvas in the sky. Understanding cloud formation requires examining the physical processes that transform invisible water vapour into visible condensed droplets or ice crystals.

Cumulus Clouds

The Clouds Above
Cumulus are low, puffed, convective clouds formed by surface heating and uplift. They have flat bases and variable tops. The name was coined in the early 19th century and is widely familiar in art, and literature.

Clouds in Art

The Clouds Above
Clouds have long captivated the human imagination, not only as meteorological phenomena but as symbols, compositional elements, and expressive devices in art. Their forms, constantly shifting and ephemeral, have inspired painters, illustrators, and photographers to capture both their visual beauty and their symbolic meanings.

Fog Geoengineering, Strange Mists and the Science Behind a Modern Myth

Chemtrails or Contrails
Strange fogs and sudden illnesses spark fears of "geoengineered fog", yet science shows pollen, pollution and atmospheric physics explain these events without invoking hidden geoengineering schemes.

An Overview of Geoengineering

Geoengineering
Geoengineering refers to deliberate, large-scale interventions in the Earth’s climate system designed to counteract the effects of global warming. It is generally divided into two main approaches: carbon dioxide removal (CDR), which aims to lower atmospheric CO₂ and solar radiation management (SRM). Neither are currently deployed at scale, and all raise significant uncertainties.

Cirrus Homogenitus Clouds (Contrails)

The Clouds Above
Cirrus homogenitus, more commonly known as contrails, are artificial ice clouds formed by aircraft exhaust in the upper troposphere and lower stratosphere. These streaks of vapour trail behind jet engines and resemble thin, fibrous cirrus clouds.

Counting the Cost of a Nationwide Chemtrail Programme

Chemtrails or Contrails
What would it actually take to run a nationwide US “chemtrail” operation? Our analysis reveals the staggering logistics — 165 aircraft, thousands of workers, and billions of dollars each year. The numbers tell their own story.

Why Contrails Can Linger and Spread

Chemtrails or Contrails
Contrails can linger and spread because they are essentially man-made cirrus clouds formed from ice crystals at high altitude. A cloud is made of water vapour, just like a contrail. Therefore if a cloud can linger, so can a contrail. When an aircraft’s hot exhaust mixes with cold, humid air, the resulting condensation freezes, creating thin white trails.

Cloud Seeding: You can’t Just Make Rain

Geoengineering
It is impossible to manufacture rain, which depends on water vapour in the atmosphere. This is supplied by heat and evaporation from the Earth’s surface. Only when moist air cools and condenses into clouds is there potential for rain. Techniques such as cloud seeding cannot create this water; they can only encourage raindrops to form in clouds that are already primed to produce rain.

Why Humans Cannot Engineer Cyclones

Geoengineering
Cyclones, hurricanes and typhoons are among the most powerful natural forces on Earth. Each one releases more energy in a few days than humanity consumes in years. Yet online theories claim that human technology, such as HAARP or directed electromagnetic fields (EMF), could somehow create or steer these vast systems.

Cloud Seeding is Not Chemtrails

Cloud seeding and so-called “chemtrails” are fundamentally different, though often confused in conspiracy circles. Cloud seeding is a small-scale, scientifically documented technique in which aircraft introduce minute amounts of silver iodide into existing clouds to encourage rainfall; it does not involve spraying chemicals into clear skies, nor does it leave visible white streaks. Chemtrails.

Sun Dimming and SRM

Sun dimming, or solar radiation management (SRM), involves deliberately reducing incoming solar energy. A key method, stratospheric aerosol injection (SAI), disperses reflective particles to raise Earth’s albedo, similar to cooling observed after volcanic eruptions. While models suggest this could lower global temperatures, risks include ozone depletion, altered rainfall patterns, and termination shock make it a highly uncertain intervention.

The Sky Looks Different Nowadays

Chemtrail believers often argue that certain cloud types are “new” formations created by secret weather manipulation, yet this claim overlooks the long history of cloud observation. Many of the patterns they point to have been described and classified by meteorologists for decades, with some recorded in cloud atlases from the 19th and early 20th centuries.

The Psychology Behind Geoengineering Conspiracy Theorists

Belief in conspiracies such as chemtrails and covert geoengineering programmes reveals more about the human psyche than about the atmosphere. We investigate individual motives, socio-cultural triggers, cognitive biases and online networks, offering a nuanced psychology-based explanation of why these theories persist.

Special & Accessory Clouds

Not all clouds fit neatly into the ten main genera. Some appear as distinctive features or as by-products of atmospheric processes. These forms provide visual evidence of atmospheric motion or turbulence and are important signals for weather observers and forecasters.
