On the afternoon of Thursday, December 12, residents in Vila Angélica, Sorocaba (SP) witnessed a rare meteorological phenomenon known as an iridescent cloud. This colorful spectacle occurs when a thinner, translucent cloud appears above a denser cloud, creating a stunning visual effect. Such phenomena are fleeting, typically lasting only about 10 to 30 minutes, heavily influenced by the stability of the cloud formation and sunlight incidence.

According to Professor Daniel Nassif, an agrometeorologist at the Federal University of São Carlos, the specific cloud type that forms above is called a 'pileus,' while the denser cloud below is identified as a 'cumulonimbus.' The rare visibility of this phenomenon makes it a unique experience for those who happen to look up at the right moment. The occurrence is not only a stunning visual display but also an intriguing subject for meteorological study, highlighting the intricate dynamics of cloud formations and atmospheric conditions in the region.

The phenomenon captures the beauty of Brazil's diverse weather patterns and draws interest from both locals and meteorological enthusiasts. Events like this emphasize the importance of observing natural phenomena, as they offer insights into the complexities of the atmosphere and can further engage the community in discussions about climate and weather science.
