In the journal Science, a team led by the Alfred Wegener Institute put forward a possible explanation in their study for the rise in global mean temperature: our planet has become less reflective because certain types of clouds have declined.

Researchers find that part of the temperature rise in 2023 is due to a decline in low altitude clouds in the northern mid-latitudes and the tropics.  In particular temperature rises in the eastern side of the North Atlantic seem likely due to a reduction in clouds like marine Stratocumulus.

Clouds form when water vapour condenses or freezes around tiny particles, called cloud condensation nuclei, that are suspended in the atmosphere. These particles are hygroscopic, meaning they attract water. Examples of cloud condensation nuclei, also called cloud seeds, include dust, ocean salt, and sulfuric acid particles. Often, entirely new particles are formed in the atmosphere to create cloud condensation nuclei. It was previously thought that most of these new particles originated in the region of outflow winds from large convective clouds, like Cumulonimbus, at the top of the troposphere. But a recent study published in the journal Science suggests that another mechanism may also be at play – one that creates new particles in even more abundance.

The troposphere is the lowest layer of Earth’s atmosphere. It is where our weather happens, and it is also the region of our atmosphere where most of our clouds form, largely because it contains the most water. By contrast, the layer above the troposphere, known as the stratosphere, is typically very dry, and so only a few specific clouds are able to form up there. While these two atmospheric layers are distinct, they can sometimes mix with each other. One type of mixing occurs when a meandering jet stream causes the stratosphere to dip into the troposphere, a phenomenon known as stratospheric air intrusion, and this seems to be a major source for the creation of cloud condensation nuclei.

The stratosphere is rich in ozone, a highly reactive molecule. When this dry, ozone-rich air of the stratosphere intrudes into and mixes with moist upper tropospheric air, other highly reactive molecules known as hydroxyl radicals are created. These hydroxyl radicals in turn mix with sulfur dioxide, which is found in abundance high in the upper troposphere, to form tiny particles of sulfuric acid – just right to serve as cloud condensation nuclei.

This new research provides new insight into the formation and properties of clouds and how they regulate incoming and outgoing solar radiation. As such, it is a step towards a better understanding of the role clouds play in our changing climate.

Science Direct has published this informative article that goes into further detail about this important discovery.

On May 28, 2024, the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) teamed up to launch a 3-year mission called EarthCARE in order to profile Earth’s clouds to see what effect they are having on climate change.

Different cloud formations interact with sunlight in different ways. For example, the low, thick, and puffy Cumulus and Stratocumulus clouds act as giant reflectors, pushing solar radiation back into Space, whereas the high, thin ice-crystal clouds Cirrus and Cirrostratus allow sunlight to easily pass through them but act as giant blankets, trapping in the Earth’s radiation and thus warming surface temperatures. Tiny particles suspended in the atmosphere, known as aerosols, also either reflect or trap solar radiation. It all depends on their composition. Some of the tiny particles are natural, such as desert dust or sea salt, and some unnatural, such as pollution. The aerosols are also crucial in the formation of clouds, for they’re the seeds onto which all cloud droplets and ice crystals form.

But scientists have a long way to go when it comes to understanding the complex interaction between clouds, aerosols, and solar radiation. This is where EarthCARE comes in.

Launched at California’s Vandenberg Space Force Base aboard a Falcon 9 rocket, EarthCARE, an acronym which stands for Earth Cloud Aerosol and Radiation Explorer, is equipped with a variety of instruments able to make 3D profiles of clouds and aerosols in our atmosphere, measuring their compositions and relationships with both reflected solar and emitted thermal radiation, ultimately providing scientists with a better understanding of the role clouds and aerosols play in the global climate.

Along with all this, EarthCARE will be able to provide meteorologists with valuable weather information, such as the speed of precipitation falling from clouds and the intensity of updrafts within Cumulonimbus storm formations – an important indicator of thunderstorm severity.

On August 2nd, UK-based soundscape artist Justin Wiggan is releasing Skydentities: Cloud Scanner the first album of music generated by clouds. The tracks were produced using a device, known as a cloud scanner, that was created by Wiggan in collaboration with artist-engineer Dominick Allen. The device collects light and colour from the clouds converting them into electrical signals to trigger musical notes via synthesisers. This setup allows musicians to use the cloud-generated data as a foundation for their performances. Wiggan invited select guest musicians to respond to the cloud-generated sounds, interpreting the sonic characteristics of clouds in real-time.

Wiggan, who also worked with the Cloud Appreciation Society to create the Memory Cloud Atlas to collect views of the sky on Cloud Appreciation Day, has named the tracks on Skydentities after each of the ten main cloud types. The album, he says, is “centred on our profound connections with the skies.” He hopes the music, inspired and created by clouds, will “encourage listeners to engage with nature and their surroundings in meaningful ways to take skies into people’s daily mindfulness routines as part of new wellbeing rituals.”

Skydentities is released on August 2nd and can be pre-saved now.

You can already listen to Altocumulus, the first track on the album.

Tom Bean, Member 41,135 has shared details of an art exhibition CUMULUS: THE ART OF METEOROLOGY, that’s opening in Flagstaff, Arizona on June 29.  The exhibit will run for three months and coincide with the arrival of the Southwest US Monsoon Season.  He told us “While Flagstaff, is a small city, it is the jumping off point for many of the 5 million annual visitors who come to see Grand Canyon National Park.  This exhibit would be of interest to CAS members, who come from all around the world.“

A small-scale experiment was recently carried out by a team at the University of Washington to explore a potential tool in the fight against the climate crisis: marine cloud brightening. The idea is that spraying tiny particles of sea salt into marine Stratocumulus clouds – the low, clumpy layer cloud that can form over large bodies of water – might encourage them to form more droplets of smaller sizes and thereby appear brighter by reflecting more sunlight. This, the argument goes, would reflect the Sun’s heat back up into Space, helping to cool the oceans below.

This first experiment of its kind in the US was conducted on the deck of a ship in Alameda, California, where the team sprayed into the air a mist of sea-salt particles to see how their size would be affected by different atmospheric conditions. The crucial aspect for the team is for these sea-salt aerosols to be just the right size to encourage the cloud droplets to form. If the salt crystals are too small, they’d be ineffective; too large, and they could potentially make clouds less reflective rather than more.

The experiment has not been without pushback. Some have argued that projects like marine cloud brightening represent a stopgap measure that would distract from tackling the root causes of climate change. Others have raised concerns about the potential for unexpected side effects were we to try to change the nature of cloud cover over large areas. According to the lead scientist in the project, Dr. Robert Wood, another decade of testing and trials would likely be needed before marine cloud brightening is even something that could be implemented at any scale.

The next phase of this experiment is for the team to start to quantify any effects the particles of sea salt have on cloud reflectivity out in the open ocean.

To read more about this test, and marine cloud brightening in general, here is an article by The New York Times and another by the University of Washington itself outlining further details.

The prehistoric peoples of the Colorado Plateau in the southwest United States knew a thing or two about clouds. And they shared their knowledge in the form of ‘cloud beings’ drawn and carved onto rocks that are still visible today…

This beautiful book about clouds by Nikki McClure is about the imagery she used to bring to life a long-forgotten television script by Rachel Carson, ‘Something About the Sky’ which aired on March 11, 1956.  Nikki approached Rachel Carson’s estate and they granted permission for her to illustrate and publish the script.  She explains that it’s full of Carson’s thoughts about the sky, and now it has become a book-shaped ‘something’ to inspire cloud gazing and wonder.  The illustrations by Nikki McClure are mesmerising and this article shows how she created them.

A recent study has shown that Cumulus clouds begin to disappear during partial solar eclipses. The study, published in the journal Communications Earth & Environment in early February 2024, used satellite cloud measurements from three solar eclipses between 2005 and 2016, and the results showed that Cumulus clouds over land began to dissipate when around 15% of the Sun’s disc was obscured by the Moon. This is because Cumulus clouds feed off columns of rising air, called thermals, and these rising thermals are formed by the heat of the Sun shining down onto the ground. As the Sun begins to be obscured, less of its heat reaches the ground, halting the formation of Cumulus clouds. This halting is, however, only temporary, for Cumulus begin to form once more after a solar eclipse has passed.

The findings of this study show that scientists may be underestimating the amount of solar radiation that reaches Earth during solar eclipses, for low, thick clouds, such as Cumulus, tend to reflect solar radiation and have a cooling effect on the planet. That solar eclipses affect cloud cover has implications with proposed climate engineering techniques. As Victor Trees, one of the researchers who worked on the study, said: ‘This could be a warning for climate engineering. If we eclipse the Sun in the future with technological solutions, it may affect the clouds. Fewer clouds could partly oppose the intended effect of climate engineering, because clouds reflect sunlight and thus actually help to cool down the Earth.’

The English word ‘cloud’ stems from the Old English clūd, meaning ‘boulder’. It is therefore fitting that the clouds on distant exoplanet WASP-107b are made of particles of silicate – minerals that are often the main constituents of sand. It is thought that the sand on WASP-107b behaves in a way reminiscent of Earth’s own water cycle: particles of silicate form clouds in the upper atmosphere. These particles then rain back down into the hotter layers of the planet’s atmosphere below, where they evaporate. In its gaseous phase, the silicate then rises and condenses back into the solid particles of cloud. This process then repeats in cycles, rather like the water cycle on Earth – but with sand!

NASA’s James Webb Space Telescope was used to carry out this research. It is the first time the chemical composition of another planet’s clouds has been detected, and its findings provide a unique insight into both the differences and similarities that can exist on planets other than our own.

An exhibition showing clouds portrayed in both art and photographic form is currently happening in Zürich, Switzerland, running until March 10, 2024.

A collaboration between the Image Archive and the Graphic Collection of ETH Zürich, the exhibition covers different printmaking techniques involved in cloud imagery, as well as asking philosophical questions about the very nature of capturing images of clouds. As the official press release says, ‘Constant movement and ever-changing form are of the essence of clouds. Their mobility and variety make them impossible to pin down – yet, by the same token, clouds can be anything: from the sublime embodiment of longing and an ominous portent, to the dwelling of the gods, to a mere accumulation of condensed water. But if the essence of clouds consists in their perpetual motion and formal metamorphosis, how can they be captured in an image?’

Emily Fischer is an editorial fellow with Midstory, a non-profit ‘thinkhub’ in the Midwest which encourages the exchange of ideas and envisions the future of the region through multimedia storytelling.  She contacted us as she was working on a story about how asperitas clouds have been seen across the Midwest and wanted to include information about the cloud’s official recognition.  Society founder, Gavin Pretor-Pinney was pleased to help and worked on the story with Emily, sharing with her the background to its recognition and describing it as “Very much like the surface of the ocean when you’re underneath, looking up. But not on a kind of calm day with regular waves — more on a chaotic, choppy day”.  Emily told us “I’m so honored to have your perspective as an integral part of its discovery!”

We tend to think of clouds as being an Earth-based phenomenon, but they also exist on other planets. On Neptune, the Solar System’s furthest planet from the Sun, cloud coverage appears to correlate with the 11-year solar cycle. The blue ice giant planet is usually covered in bands of white cloud, which become more frequent two years after the solar cycle’s peak, where the Sun’s activity increases. However, since 2019, the clouds have been disappearing, with latest imagery from the Keck II telescope showing clouds being found only on the planet’s southern pole. ‘This is extremely exciting and unexpected, especially since Neptune’s previous period of low cloud activity was not nearly as dramatic and prolonged,’ said Erandi Chavez, of the Center for Astrophysics | Harvard-Smithsonian (CfA).

Clotilde Wang, Member 37,435, recently told us about a French broadcast entitled “Head in the Clouds”.  The translated programme description states:

“At the beginning of autumn, the course of the clouds parades, carrying showers and clearings. If we cannot grasp them with our hands, we can nevertheless grasp them through the arts and sciences. From the mapping of clouds, which reveals their territories to us, to meteorological engineering, which makes it possible to make rain fall, through their pictorial and poetic study, we learn to know them better”.

Noctilucent clouds, also known as polar mesospheric clouds, are ice-crystal formations found in a region of the upper atmosphere called the mesosphere. They form at altitudes of 50 miles (80 km), right up near the fringes of Space, making them Earth’s highest clouds. Named with the Latin for ‘night shining’, they have a bluish glow as they catch the light when the rest of the sky is dark. The clouds are seen only during twilight hours when the Sun is below the horizon (between 6° and 16° below, to be precise). They are only visible during summertime, and from mid-to-high latitude regions of the world.

Over the past few decades, sightings of noctilucent clouds have become more frequent. They have been seen from more extensive regions, appearing further south in the Northern Hemisphere, for instance. It is possible the increasing frequency of this mysterious and ghostly formation is a consequence of our warming climate.

Heike Negenborn, Member 8,845, an artist from Windesheim, Germany currently has a solo exhibition entitled “Landscape Stories” at the Galerie Hübner & Hübner, Frankfurt.  It’s running from 17th March to 22nd April 2023.

The subtitle of this Netscape is “Changing Landscape”. The artist explaineds “In the series of monumental overview landscapes, which were awarded the Palatinate Prize for Fine Arts and the Wilhelm Morgner Prize, I combine cloud and earth fragments with perspectively fanned-out grids, which transform into digital pixels dissolve and mutate into network landscapes, into Netscapes. The reshaping of the cultural landscape is underpinned by the reduction of my otherwise strongly colored palette to black and white tones and by the depiction of the landscape as a construct. Clearly visible construction and perspective lines reveal my strategies and support the depth effect in the picture. The works deal with the relationship between nature, its image and its multimedia transfer possibilities.”

King of Clouds and a special bonus episode about Luke Howard

When a cloud of iridescent colours and eyebrow shapes drew a crowd in the Himalayas…

Monday November 28, 2022 was the 250th anniversary of the birth of English chemist and amateur meteorologist Luke Howard, the man who named clouds. On a cold December evening in 1802, this modest young Quaker presented a lecture called ‘On the Modification of Clouds’ to members of his scientific debating club in London. Howard had loved the sky ever since he was a young child, and he proposed in his talk a system for naming the recognisable forms of clouds with Latin terms like those used for plants and animals. For millennia, a consistent and systematic way of referring to cloud types had eluded great minds. Many insisted clouds were too chaotic and ephemeral to be classified, or that naming them served no purpose. But the simple, science-based system of classification Howard proposed struck a chord not only with his audience that night but soon with an international scientific community and even with poets and artists. Luke Howard, much to his discomfort, became a celebrity across Great Britain and Europe. He was applauded for opening people’s eyes to the recognisable forms of the sky and for successfully arguing that Latin terms would provide a lexicon to ensure consistency across international weather observations. Howard’s naming system, now codified and maintained by the UN’s World Meteorological Organization, still remains the official system used worldwide. This week we are theming our Cloud-a-Day emails on ‘Father of Meteorology’ Luke Howard to mark the influence he had on the sciences, the arts, and on everyday people looking up when he forged a new language for the sky.

This portrait of Luke Howard, likely painted by John Opie in c. 1807, is in the collection of The Royal Meteorological Society in Reading, England.

Ann Kraus, Member 48,329, is holding a solo show at Pleiades Gallery in NYC from November 29th to December 24th 2022.  She explains on her website  “Clouds are a key subject in my skycap paintings. These omnipresent and ethereal gifts of nature are dynamic, poetic and can sometimes mirror our own emotions. The clouds are constantly evolving as they are buffeted by the wind and add drama and clarity to our world at sunrise and sunset. Being focused and cloud aware is certainly a needed antidote for our downward gaze at our digital screens”.

Edward Graham, editor of Weather, and Gavin Pretor-Pinney (Member 001), wrote the article “When Clouds Raise an Eyebrow – the case for a new supplementary cloud feature ‘Supercilium‘” to celebrate 250 years since the birth of Luke Howard.  Supercilium are short-lived cloud features, which appear in turbulent airflow over, and to the immediate lee of, steep mountain peaks during periods of strong mountain summit level winds.  The image shown here was used as our March 2022 Cloud of the Month.

Artist, Justin Wiggan, has started a crowdfunding campaign to fund the creation of a Cloud Scanner device to turn the appearance of clouds into sounds and haptic feedback for visually and hearing impaired children.  He told us:

“The sky should be the most accessible thing of all so I’ll build a working prototype of a handheld device called a cloud scanner which reads clouds and converts the signal into sound which is then converted to a haptic signals which can be felt.

The funds will go on development of the tech , parts and testing so that children with sight impairment can hear and feel the clouds and allowing this accessibility to the sky for these children will have a major impact in wellbeing.

Climate action awareness sometimes forgets to include those who may be overlooked due to physical disabilities .

Cloud scanner allows a channel to trigger emotive and empathetic conversations leading to behaviour change in children that are sight impaired or blind. This gives a voice to those”.

Diana Ewer is curating an exhibition of Skyscape cloud paintings by American artist Jon Schueler (1916-1992) entitled “Reflections on the Sound of Sleat”. The exhibition will be at the Caledonian Club, London and will run from 29th September to 4th November 2022.

The official press release reads:

“Jon Schueler: Reflections on the Sound of Sleat” on view in the Caledonian Club’s newly renovated drawing room from 29th September presents a seminal exhibition of Scottish abstract skyscapes. Described as “A home away from home for Scots in London”, the club would undoubtably have appealed to the late American painter Jon Schueler (1916-1992) who was a Caledonophile at heart.

A member of the Second-Generation Abstract Expressionists, whose mentor at the California School of Fine Arts was Clyfford Still (1948-1950), Schueler, having achieved both critical and financial success in New York with the Leo Castelli Gallery, set off to the Western Highlands in 1957. Settling in the small fishing village of Mallaig, he found in the Scottish landscape, most notably in the Sound of Sleat’s weathering skies, a source of intense feeling and expression that would become a constant touchstone and enduring influence on his paintings. In 1970 Schueler returned, to establish a new studio at Romasaig, a former schoolhouse by the sea, just a mile from Mallaig. The artist would paint there year after year until his death in 1992.

These seven Romasaig skyscapes from the 1970s and 1980s are as vibrant as the day they were painted and can be interpreted as distillations of Schueler’s direct experience of the constantly shifting weather. These works are deeply personal, revealing through layer upon layer of paint, an artist who tirelessly dedicated himself to capturing the evocative and fleeting moods of the sky on canvas. “In Scotland, I have looked each day at the lonely horizon, at that line (or is it a line?) where the sea and the sky meet. I have tried to understand it and tried to know how to paint it and what the painting of it might mean. I have seen the light immediately above and I have seen the light immediately below. I have tried to understand the shadow and the reflection upon reflection.” I But these paintings also hold a universal appeal, especially resonating with those who are familiar with the ever-changing dramatic sea and skyscapes of the Isle of Skye and beyond.

“Building on the artist’s recent London retrospective in 2019 at Waterhouse & Dodd, it is an honour to show Jon Schueler’s paintings in the company of the Caledonian Club’s own fine art collection. We hope the show will encourage further interest in the artist’s work, and that Schueler’s skyscapes will strike a deep emotional connection with those familiar with the coast of the Western Highlands.”
Diana Ewer, Curator for the Jon Schueler Estate.

CGI artist and painter, Matt Wilson, has sent in his series Surreal Cloudscapes.  Matt created the CGI cloudscapes in the recent ‘Lightyear’ Pixar movie, but during Covid isolation he began experimenting with creating cloudscapes on his own.  He calls his art series Sentinels, and they were recently featured in the Solo Show in New York City. 

Matt explained to us how he goes about creating clouds on computers.  “Clouds are elusive creatures”, he told us, “and as such require a wide spectrum of methods to represent their forms and movement. Even with today’s massive computing power they still push the edge of the technology, which for me reiterates their magic out in the real world. In movies, television or games, any time you see a puff of smoke, or a cloud or fog or any “volumetric” effect, they are typically represented by something called “voxels”, or volume pixels. Essentially little cubes filled with a certain amount of “density” or a given substance (water droplets, smoke, etc)… often billions of them (yes that does take up a LOT of data storage).  You can stack those cubes into a shape by either sculpting it into place, like a sculptor with clay, or you can use the much more complex process of using physics simulations to choreograph the volume into place. Both are equally fun but the later of the two gives you the opportunity to try to understand the underlying physics”. 

We asked Matt to explain how he references real clouds when sculpting his digital ones.  “

Observation and understanding are my first steps,” he explained.  “Combing through the years of C.A.S. images, google image search and my edition of the cloud spotters guide is usually where I begin. I go about my simulation setups by trying to evaluate the source of humidity from the ground up and then the surrounding atmospheric conditions; temperature gradient as the cloud rises up in the air, sheering forces and turbulence. Mammatus undulatus is a great example of a cloud formation where the shape of the turbulence is much easier to visually see, relative to other more complex cloud types like cumulus fractus. You can think of the overall cloudscape as a recipe… a combination of several of types at various altitudes. You begin with a big cumulus congestus formation built using a simulation surrounded by some hand-placed, sculpted, cumulus humilis clouds and “ice the cake” with a layer of altostratus clouds that can be sculpted using some fractal math”. 

We think the clouds are really convincing and we’re so pleased that the real clouds on the CAS Photo Gallery have served as inspiration.
