Clouds sometimes appear to have recognizable shapes due to the variation in atmospheric pressure, humidity, and air movements that influence their formation and structure. These factors help create familiar visual patterns such as animals, objects, or geometric shapes.
Clouds are primarily made up of droplets of water or small crystals of ice suspended in the air. Their shape mainly depends on the movements of warm air rising, encountering cold air higher up, and then cooling in turn, thus promoting condensation. These air movements are never regular or uniform, which explains why clouds take on varied, and sometimes even bizarre, shapes. Turbulent currents, different levels of humidity, or rapid temperature changes continuously shape these unexpected silhouettes. It is this cocktail of unstable currents, humidity, and moving temperatures that presents your surprised eyes with clouds that are sometimes surprisingly recognizable.
Drafts, temperature, and humidity directly shape the various forms of clouds. When warm air rises, it cools and then condenses water vapor into tiny droplets. Depending on how this ascent occurs, whether slow or abrupt, you will have smooth clouds or very turbulent ones with all sorts of quirky shapes. When layers of wind blow in different directions or at different speeds, clouds stretch or deform oddly, creating those unexpected shapes that tend to resemble familiar silhouettes. Even the sun has a say: the light, depending on the angle at which it hits these suspended droplets, highlights certain shapes, softens others, and sometimes creates a downright optical illusion before your eyes.
Our brain loves to find familiar shapes even where there aren't really any. That's the phenomenon of pareidolia: a kind of charming little bug where our mind sees objects or faces in random structures. It happens with clouds, but also with a slice of toast or a stain on the wall. Basically, our brain tries to organize the surrounding chaos into understandable patterns to reassure itself or quickly detect faces, which is essential for survival. So when you look up at the sky and think you see a dog, a face, or a dragon in the clouds, it’s just your overzealous brain working as usual.
The shapes we notice in the sky depend greatly on our culture. Each culture has its own myths, popular stories, or specific visual references that directly influence what it identifies in the clouds. For example, where a person from Western culture might see a sheep or a rabbit, someone from another region of the world might more spontaneously recognize a legendary animal or a local deity. This cultural variation is based on the fact that our brain automatically recognizes familiar shapes from our personal, social, or cultural universe. In other words, perception is filtered by our habits, our learnings, and our repeated exposure to certain specific visual representations.
We often see an elephant or a rabbit in the cumulus clouds because these low, fluffy clouds are constantly changing as they form and dissipate: they easily take on rounded and irregular shapes that resemble our representations of familiar animals or objects. The famous fish-shaped clouds often emerge in lenticular altocumulus clouds that appear when moist air is pushed upward by a mountain: their elongated shape similar to a fish or a saucer is quite common. For very clear human faces or profiles in the clouds, the culprit is usually a stratocumulus or a cumulonimbus, which are quite dense and thick clouds that cast contrasting shadows, thereby highlighting familiar features that our brain immediately picks up on.
A scientific study indicates that regularly observing clouds and looking for familiar shapes can help reduce stress and improve concentration, thanks to its relaxing effect.
The photographer Alfred Stieglitz is famous for having taken an entire series of cloud photographs entitled 'Equivalents' at the beginning of the 20th century, pioneering the abstract artistic representation of cloud formations.
Some artists and philosophers of the Renaissance believed that observing clouds stimulated the imagination and creativity, recommending this activity as a means to find artistic inspiration.
The cloud formations resembling flying saucers, known as altocumulus lenticularis, are responsible for many UFO sightings. These cloud formations typically occur near mountains.
To achieve remarkable cloud photographs, favor a wide angle, adjust your exposure to capture the subtle nuances and contrasts of the clouds, and make sure to take shots during times when the light is soft (sunrise or sunset). Additionally, being patient allows you to capture very original and ephemeral cloud formations.
Yes, the shapes perceived in clouds are often influenced by culture, beliefs, and the environment in which individuals live. Thus, the same cloud formation may evoke a completely different object for someone from a different culture.
Sure! Here’s the translation: "Yes, to a certain extent. The shape, height, and density of clouds can provide valuable clues about short-term weather conditions. For example, the formation of increasingly dense and towering cumulus clouds may indicate the approach of a storm. However, specific shapes (like a silhouette of a dog or a dragon) obviously have no direct relation to the weather!"
Cumuliform clouds, such as cumulus clouds, often give rise to the most evocative shapes. Their dense structure and rapid evolution lead to the formation of a wide variety of outlines that our brain easily interprets as recognizable objects or characters.
This phenomenon is called pareidolia, a natural tendency of our brain to attribute familiar shapes to random structures like clouds. The human brain is predisposed to quickly identify familiar visual elements, such as faces or animals, even when they do not actually exist.
