The town of Trondheim in Norway were bedazzled when a huge mushroom shaped cloud appeared over a mountain nearby, which had the striking resemblance of the cloud formation from a nuclear blast.
Retired Professor of physics, Dr Løkberg, witnessed the odd cloud and took some photos of it:
The cloud have eerie similarities to nuclear tests, but the town is still standing. Mushroom clouds are normally shaped when a powerful explosion creates a crater which focuses heat and airflow directly upwards. The "hat", or top of the mushroom cloud, is shaped by the upward stream as it stops.
"It started to float slowly towards the mountain where it stopped up and turned into a real huge mushroom shaped cloud. I ran to grab my camera and shot several photos of it. It looked like terrible things were happening over there, but the cloud slowly dissolved and disappeared." Løkberg said.
"Really spectacular. It certainly looks like doom day is at hand." meteorologist Roar Hansen at Storm Weather Center jokingly says.The meteorologist further explains that he believes the cause behind this strange phenomena might be due to the very unstable air masses above the town. He believes that an increase in temperature around 3000m above ground made the cloud flatten out at the top forming this peculiar mushroom cloud formation.
