Residents of Pico Truncado, a small town in Argentina, were terrified by a giant cloud covering several kilometers that covered the sky over the entire city.
The case took place on December 27, 2020, but only now have the images begun to spread across the internet.
Not knowing for sure what the strange phenomenon was , the residents ended up creating several bizarre theories about what the cloud would be, and of course many of these conspiracy theories spread around the world.
But what is this strange cloud that looks like a nuclear bomb anyway?
According to experts, these formations are called roller clouds , or Volutus clouds . They are defined as a long cloud mass, usually low, isolated and tubular.
Clouds of this type are formed by storms with winds that change speed or direction during a natural phenomenon that scientists call “inversion”, when the air temperature changes and leaves warm air on top of a layer of cold air.
Volutus clouds are not very common, but they are not exactly rare either, and have been sighted in several countries such as Australia, Russia and the United States.
In Uruguay, a similar phenomenon occurred in 2019 and also intrigued residents. But by now you know that this is just a relatively rare natural phenomenon .
