A breathtaking iridescent cloud over Bogor, Indonesia, went viral last week, captivating viewers with its stunning colors. Residents of Jonggol spotted the rainbow clouds, which are a rare atmospheric phenomenon related to atmospheric optics.
Ida Pramuwardani of Indonesia’s Meteorology, Climatology, and Geophysics Agency (BMKG) confirmed the occurrence. She stated, “The phenomenon seen in the video is a common occurrence in the atmosphere and is related to atmospheric optics.” This statement emphasizes that such events are not entirely unusual but still awe-inspiring.
Iridescent clouds occur when sunlight diffracts off ice crystals in the atmosphere. This phenomenon requires specific conditions to manifest, often linked to cumulonimbus clouds and enhanced by the presence of a pileus cap—a type of lenticular cloud that provides the consistent droplets necessary for iridescence.
The colors of these clouds can change rapidly and may appear in various hues including pink, green, and blue. The sighting in Bogor aligns with previous reports of iridescent clouds observed in Malaysia, Vietnam, and Singapore over recent years.
Key characteristics of iridescent clouds:
- Iridescent clouds can be confused with nacreous clouds and coronae.
- The colors can shift quickly and may not last long.
- They typically occur near where the sun appears—making direct observation potentially dangerous.
This captivating weather phenomenon sparked curiosity among locals and went viral on social media platforms. Iridescent clouds have been documented since at least 1911 when they were painted by Edward Wilson in Antarctica.
As awareness grows about this beautiful display of nature’s artistry, more people might start looking skyward for similar occurrences. The next opportunity for such sightings may depend on local weather conditions conducive to this unique atmospheric event.
