Does this cloud look like a mushroom in the sky? It appeared over Russia last month and had locals fearing that “doomsday” had arrived.
To many locals, the clouds looked like the ‘mushroom cloud’ of a nuclear explosion. The emergency services for the Siberian city of Kemerovo were deluged with calls.
While some feared a nuclear strike, other thought it might be an explosion in one of the nearby coal mines. The media started calling it the Siberian “Cloud of Doom.”
However, this ‘mushroom cloud’ was just a cloud, albeit a massive cumulonimbus cloud.
Fortunately, no one had declared war against the Siberian woodlands. Authorities were able to reassure the local residents that this unusually large cumulonimbus
cloud was perfectly natural.
WHAT IS A CUMULONIMBUS CLOUD?
Supercell storms are the strongest of thunderstorms, able to sprout tornadoes. (Indeed, within that week, Russia had a rare tornado rip through the city of Syktyvkar and
reports of a tornado or water spout near the former Russian Olympic city of Sochi.)
The supercell storm cloud swirls as high as 55,000 to 70,000 feet above the ground and is topped by a spreading cloud mass called an anvil. If the updraft is strong and
narrow enough, it can look like a mushroom cloud.

(Side note: I pulled off the road last year as one of these cumulonimbus monsters grew like a mountain growing before my eyes. Cars and people were around me
and not one other looked up and gawked at that marvelous thing with me. I felt like I was in the presence of well, fuck, if not the Godz then I have no words for it.)
