Stormchasers capture evolution of supercell thunderstorm


Stormchasers in the US have captured the evolution of a huge “supercell” storm from its formation until it disappears.

The stunning time-lapse, which has been viewed almost 2.5 million times, shows a mass of swirling clouds tighten into a rotating column reaching out of sight into the clouds.

As the storm grows larger, the chasers move away to reveal its size as it spins, dropping torrential rain, before the funnel unfurls and the clouds dissolve.

The group, Basehunters, tracked it for almost 70 miles from Wright to Newcastle in Wyoming on Sunday.

Supercells are also known as rotating thunderstorms and are the least common and most violent storms.

They are often found in the Great Plains of the US, where they cause much of the severe weather in the area known as Tornado Alley.

One storm can spawn several tornadoes in its lifespan and produce large hail, damaging winds, flooding, powerful lightning and heavy rain.
