This week, residents of Matanzas were taken by surprise by a striking display of mammatus clouds, a spectacle captured in a photograph by meteorologist Henry Delgado Manzor. He shared the image on social media, offering an insightful explanation of this rare atmospheric phenomenon.
"Mammatus clouds grace the skies of Matanzas! Their intriguing name comes from the Latin word 'mamma,' meaning 'breast' or 'udder,' due to their unmistakable hanging, lobe-like shapes," Delgado Manzor noted on his Facebook page.
The photo reveals numerous rounded protrusions hanging beneath a vast cloud layer, bathed in hues of blue and pink, creating an extraordinary scene over the city.
Understanding the Formation of Mammatus Clouds
Also referred to as mastodon clouds, mammatus are not a distinct type of cloud. They manifest on the underside of large storm clouds, especially cumulonimbus clouds, when cold air masses descend and mix with warmer, unstable air.
According to National Geographic, these formations are named for their resemblance to bags or breasts and are relatively easy to spot due to their distinct appearance.
Implications for Aviation and Weather Patterns
Despite their often ominous look, experts clarify that mammatus clouds do not cause tornadoes and are not dangerous by themselves. They typically arise from fully developed storms and often suggest that the worst of the weather may be over or moving away.
In aviation, however, they warrant attention as they can be linked to strong updrafts and downdrafts capable of causing severe turbulence.
Delgado Manzor is no stranger to capturing unusual atmospheric events over Matanzas. In May 2022, he documented a fallstreak hole, and in July 2025, he photographed an episode of iridescence that also intrigued meteorology enthusiasts.
Seasonal Patterns and Natural Beauty
Summer is the prime time for observing such formations in Cuba. From May to October, increased storm activity leads to the development of large cumulonimbus clouds, the typical origin of mammatus.
The meteorologist's photo once again highlights that beyond the rain and storms typical of the season, the Cuban sky can also offer breathtaking natural spectacles that captivate both experts and enthusiasts alike.
Exploring Mammatus Clouds and Their Impact
What causes mammatus clouds to form?
Mammatus clouds form beneath large thunderstorm clouds when cold air descends and interacts with warmer, unstable air, creating their characteristic hanging shapes.
Are mammatus clouds dangerous?
While their appearance might seem threatening, mammatus clouds do not cause tornadoes or pose any direct danger. They are simply indicators of storms that have already developed.
Why are mammatus clouds significant for aviation?
In aviation, mammatus clouds are noteworthy because they may be linked to strong air currents, leading to severe turbulence, which presents challenges for pilots.
