Pyrocumulonimbus Clouds

Pyrocumulonimbus clouds are thunder clouds created by intense heat from the Earth’s surface. They are formed in a very similar way to cumulonimbus clouds, but the intense heat that results in the vigorous updraft comes from fire, either large wildfires or volcanic eruptions. It is for this reason the prefix ‘pyro’ is used – meaning fire in Latin. Pyrocumulonimbus clouds were reported during the Australian bushfires in late 2019/early 2020 and a number have more recently been observed in Siberia with the Arctic heatwave.
