Rare Asperitas Clouds Ripple Over Ottawa’s Skies, Creating a Stunning Visual Phenomenon
Residents of Ottawa were treated to an extraordinary natural spectacle on Sunday evening as rare asperitas clouds formed and rippled across the sky. These striking cloud formations, resembling ocean waves suspended in the atmosphere, are known for their undulating, rough appearance and have become a fascination among weather enthusiasts. The clouds were captured in stunning video footage by CTV News Ottawa’s Matt Skube, with the dramatic display visible over the city’s west end.
Asperitas clouds are a relatively recent addition to the world of meteorology. They were first proposed by the Cloud Appreciation Society in 2008 and gained formal recognition by the World Meteorological Organization (WMO) in 2015, becoming the first new cloud type added to the WMO’s prestigious International Cloud Atlas in over 50 years. Their Latin name, “asperitas,” meaning roughness, fittingly describes the turbulent, wave-like formations that make these clouds so distinctive.
What makes asperitas clouds particularly unique is their irregular, textured surface that often mirrors the appearance of ocean waves during a storm. While their aesthetic appeal is undeniable, scientists continue to study their formation and behavior to better understand the meteorological conditions that lead to their development. It is believed that asperitas clouds form when cooler pockets of air sink and interact with warmer air, combined with wind shear, creating the swirling, wave-like structures that ripple across the cloud’s base.
The visual drama of asperitas clouds is not a common sight, and their appearance over Ottawa is a rare occurrence that has left many residents and weather enthusiasts in awe. These clouds are often associated with turbulent atmospheric conditions, but they don’t necessarily signal severe weather. Instead, they are more likely to occur after a storm has passed or during periods of instability in the atmosphere.
Sunday’s cloud show has drawn attention to the beauty and mystery of asperitas clouds, a formation that has only grown in recognition since it was first identified. The Cloud Appreciation Society, a group dedicated to the beauty and study of clouds, has long championed the inclusion of asperitas in the official cloud classification system. Their efforts came to fruition when the WMO accepted asperitas clouds into the International Cloud Atlas, marking a significant milestone in cloud science.
Videos and photographs of the asperitas clouds over Ottawa have since been widely shared, showcasing the waves of clouds rolling across the sky, creating a breathtaking canvas of nature’s complexity. The sight was both eerie and enchanting, with the undulating clouds giving the impression of a restless ocean captured above the horizon.
Meteorologists believe that understanding cloud formations like asperitas can offer insights into weather patterns and atmospheric changes. While these clouds do not pose any immediate weather threats, they symbolize the dynamic nature of our atmosphere and highlight the continuous movement and interaction of air masses that shape the weather we experience on Earth.
As more people become aware of the beauty and significance of rare cloud formations like asperitas, there is a growing appreciation for the diversity of cloud types and their role in weather observation and forecasting. Whether viewed by weather enthusiasts or curious residents, asperitas clouds continue to inspire awe, wonder, and a deeper connection to the natural world.
The rare cloud display over Ottawa serves as a reminder of the extraordinary phenomena that nature presents, often without warning. For those lucky enough to have witnessed it, the asperitas clouds will remain an unforgettable moment of beauty suspended in time, rippling above the skyline, leaving many to marvel at the forces of nature that created such a stunning visual spectacle.
