What are lenticular clouds? UFO shaped phenomenon in the sky.
One of the most awe-inspiring sights in nature is a lenticular cloud! If you’ve not seen them before they’re often described as a UFO shaped phenomenon in the sky, those otherworldly, saucer-shaped formations that seem plucked from a sci-fi film. As transient as they are striking, lenticular clouds capture the intersection of science, myth, and the messages the natural world sends us, if we’re tuned in enough to listen.
What are lenticular clouds?
Lenticular clouds form when stable, moist air flows over an obstacle like a mountain or ridge and creates standing waves in the atmosphere. Occasionally they can form over manmade structures too. When the conditions are just right, these waves condense at their crests, forming lens-shaped clouds. Their smooth, layered appearance often leads to mistaken UFO sightings or imaginings of celestial highways.
Lenticular clouds are stationary, fixed in place while the air moves through them, replenishing the moisture needed to maintain their structure. Their unique formation requires very specific atmospheric conditions:
- Stable air layers that flow over a topographic obstacle.
- Sufficient moisture at the altitude where the waves form.
- A sharp temperature gradient that allows water vapour to condense.
Key Features
Smooth Edges: The clouds often have smooth, well-defined edges, which can appear particularly striking against a clear sky.
Lens Shape: Lenticular clouds have a unique, streamlined shape that often resembles a flying saucer or a stack of pancakes.
Stationary: Despite strong winds, these clouds can remain stationary because they form at the crests of standing wave patterns in the atmosphere.
Types of Lenticular Clouds
Lenticular clouds can be classified based on their altitude:
- Altocumulus Lenticularis: These are the most common type and form at mid-altitudes.
- Stratocumulus Lenticularis: These form at lower altitudes.
- Cirrocumulus Lenticularis: These form at higher altitudes, though they are less common.
Lenticular clouds in the wild
Westfjords, Iceland
One unforgettable day in the remote Westfjords, the sky was alive with lenticular clouds of every size and shape, stretched like a highway across the heavens. Their layered forms mimicked the landscape below, mirroring Iceland’s rugged peaks and fjords. These clouds seemed to tell a story of movement, of wind carving invisible pathways in the atmosphere.
Lyngen Alps, Arctic Norway
In Arctic Norway, lenticular clouds take on a dramatic life of their own. One evening, as the sun dipped below the horizon, a series of lenticular clouds blazed in blood-red hues, illuminated by the low-angle sunlight for over an hour. It felt as though the clouds themselves were alive, whispering secrets of the wild and untamed Arctic skies.
Messages from the sky: folklore and meaning of lenticular clouds
Throughout history, clouds have been seen as more than just meteorological phenomena; they are nature’s messengers, weaving their way into folklore and belief systems. Lenticular clouds, with their dramatic and often surreal appearance, have inspired their share of myths.
- Celestial portals: In some cultures, lenticular clouds are seen as gateways to the divine or as omens of change, embodying the idea of the skies sending wisdom to those who pay attention.
- Weather predictors: Sailors and mountain dwellers historically regarded lenticular clouds as a harbinger of storms, understanding that the atmospheric conditions needed to create these clouds often coincided with strong winds or turbulent weather.
- UFO myths: Their smooth, saucer-like shapes have led to countless UFO sightings and theories. While modern science explains their formation, their surreal quality still sparks wonder.
Could there be truth to the folklore? Perhaps. Lenticular clouds do reflect specific atmospheric conditions—moisture, wind patterns, and temperature gradients—that often precede shifts in weather. In a way, they are a form of nature’s intelligence, signaling changes to come.
Wisdom in the wild edge
What can lenticular clouds teach us about connecting with the wild edge of our environment? They are a striking reminder of the invisible forces shaping our world—air currents, temperature gradients, and moisture levels that we can’t see but profoundly affect us.
When we pause to observe these clouds, we’re reminded of nature’s intricate dance, the unseen becoming visible, and the stories the earth and sky tell. The lenticular cloud becomes a metaphor for attuning ourselves to these subtleties, a reminder to read the messages written in the wind and let them guide us.
How to see lenticular clouds
To catch a glimpse of these ethereal formations:
- Visit mountainous or hilly regions where air currents are disrupted, such as Iceland, Norway, or Scotland.
- Look for them during periods of stable weather with strong winds aloft.
- Sunrise and sunset often bring out their most vivid colors, as light reflects off their layered forms.
Lenticular clouds remind us that the wild edge is always there, waiting for us to step into it. Whether they form highways in the Westfjords or blaze blood-red in the last light glow in the Arctic, they challenge us to slow down, tune in and recognise the messages that nature is sending us, wisdom shard up in the sky, if only we choose to listen.
Lenticular Clouds and iridescence
Lenticular clouds are already a mesmerising sight, but when they display iridescence, they become truly magickal. This rare phenomenon occurs when the cloud’s tiny water droplets or ice crystals scatter sunlight, producing a spectrum of colours similar to a soap bubble or oil slick. Iridescence is most often seen near the edges of the cloud, where the particle size is uniform and the light is diffracted at just the right angle. To witness this breathtaking display, look for lenticular clouds during sunrise or sunset, when the low-angle sunlight enhances the colors. The combination of the cloud’s smooth, lens-like shape and the shimmering hues creates an ethereal vision that feels almost otherworldly.
About me
Hi, I’m Rebecca, a photographer and storyteller captivated by the beauty and mystery of our natural world. My love for lenticular clouds is part of a lifelong fascination with the skies, weather, and the wild edges of nature where science meets awe. Growing up by the sea in Ramsgate, Kent, I’ve always been drawn to liminal spaces, those in-between places where the ordinary transforms into the extraordinary.
Lenticular clouds hold a special place in my heart because they embody that perfect mix of science and magick. As a photographer, I’m inspired by their otherworldly forms and the rare moments of iridescence that light them up with a refracted glow. Through my work, I aim to share these fleeting wonders with others, helping them see the world through a lens of curiosity and wonder. Whether I’m chasing auroras, diving beneath the waves, or watching lenticular clouds ripple over a mountain, I’m always seeking to connect people, place, and planet through the stories I capture.
