It is called Pyrocumulus or Cumulus flammagenitus and refers to a cloud formed from an intense focus of heat or a volcanic eruption. In this case, it was caused by a heat focus originated in the Sabrosa fire in Vila Real.
The Meteo page brings the Montes – Portugal shared images of a phenomenon recorded in the fire in Sabrosa, Vila Real, and has both “impressive” and “worrying”.
Pyrocumulus or Cumulus flammagenitus It refers to a cloud formed from an intense focus of heat or a volcanic eruption, with the form of a giant cauliflower.
In response to the publication there are several users, including farm far away from the fire, who also captured the cloud
But what phenomenon is this?
The word pyrocumulation results from the prefix piro- originates in the Greek term pyros, which means “fire”, in the case of “flammagenitus”, its meaning is “generated by flame or fire”, hence the choice of this name to identify the clouds generated by forest fires and volcanic eruptions.
The climb of hot air and smoke generated by the fires result in the formation of pyrocumulus – clouds of vertical development.
In the case of a forest fire, “It is the intense focus of heat that generates vigorous air ascension, mixed with gases and particles of tobacco and ashes from the burning of vegetable matter”Explains the Meteored website.
It turns out that, as “the Smoking gains height and reaches atmospheric levels where the environment is cold enough, water vapor, which in large quantities can reach the top, change of state, droplets of liquid water and ice embryos are formed and the pyrocumulus begins, adopting the shape of a cauliflower at the top”.
