Nacreous Clouds: Rare Iridescent Display in Scotland

An ethereal dance of pink, purple, and orange hues descended on a Scottish neighborhood as rays of sunlight played over high-altitude clouds. This atmospheric phenomenon, known as iridescent or Nacreous clouds, is not just a beautiful sight, but a rare one.

An iridescent sky blankets a quiet Scottish neighborhood, painting rooftops with hues of pink, purple, and orange. These are Nacreous clouds, a rare atmospheric phenomenon only visible at high altitudes. The vibrant colors are a mesmerizing dance of sunlight and ice crystals.

Iridescent Clouds and the science of light

Explorewithjoshua captures the clouds in Scotland, Nacreous clouds form at high altitudes and are distinctly rare in the UK. The vibrant colors form due to what is known as the phenomenon of iridescence. Nacreous, or mother-of-pearl, clouds look much like oil spilled on water as they are formed by sunlight refracting off ice crystals in the upper troposphere and lower stratosphere. This is different from rainbows, which are caused by light reflecting off raindrops. Nacreous clouds appear as a mesmerizing play of colors, ranging from soft pastels to vibrant hues. These typically appear as pearlescent clouds in the sky, often described as shimmering and lustrous. Nacreous clouds are seen only at high altitudes, typically between 15,000 and 25,000 meters, and is a rare occurrence. The clouds are rarest in Scotland. They are so high that they can be seen even in the UK. To see these clouds, the viewer must have a cool night, the presence of sunlight, and a window of time before dawn when the sun is below the horizon. If everything is aligned perfectly, the sun’s rays can refract and diffract around the ice crystals in the clouds, creating a mesmerizing color display. Satellites have captured these clouds from space, revealing their stunning beauty. The iridescent colors are a result of the refraction of light, much like a prism does in a rainbow. The colors of iridescent clouds are seen during their formation as small crystals emerge first, and the larger crystals disappear. The phenomenon is also known as the "irising" of clouds. However, seeing these clouds is no longer a rarity thanks to the advent of social media where photos can be captured and broadcasted in a minute.

Rising Above the Ordinary: Social Media and Atmospheric Events

Nacreous clouds might be rare, but their capture and sharing are routine. Platforms like Instagram, and more specifically the one the artist is on, have democratized nature photography for armchair travelers and professional photographers. Twitter, Facebook, and Instagram are now the go-to destinations for capturing rare atmospheric events. Once a phenomenon would make a national headline, like New York City's snowless winter or clear skies over the Empire State Building, now these events are shared and interacted on social media. The advent of social media really changed how the world views nature. Today, anyone can see Nacreous clouds in a post shared from another part of the planet. This occurs because of the sharing of images and videos on social media platforms. This phenomenon has led to a number of phenomena being captured and shared on social media, the most common of which is the iridescent clouds.

Creative Photography: How to capture iridescent clouds

Iridescent clouds are captured with good equipment, an eye for the moment, and knowing how to edit images. The first step in capturing such images is to identify the right weather conditions.

These are the most risky times to capture such images because the light of the sun during these hours is unique. The clouds begin to form and break up, giving photographers a window of just a few minutes to capture the phenomenon. Having the right gear will make capturing iridescent clouds easier. A DSLR camera, a tripod, and a wide-angle lens are all essential. These tools are essential for framing and focus on the perfect shot. Editing plays a crucial role in capturing vibrant colors in their natural beauty. The right editing software can help enhance the natural colors of the clouds. Tools such as Adobe Lightroom and Photoshop can help in adding more vibrancy to the image due to the hues.
