In the US state of North Dakota, an unusual, threatening weather phenomenon caused some surprise this weekend. A so-called supercell, a particularly strong thunderstorm cell that only occurs under certain conditions, floated in the sky like an oversized UFO (see video above).
Supercells are storm towers with vertical rotation. According to meteorologists, they form when different wind directions and strengths converge at different altitudes. What is called wind shear and what creates horizontal circulations in the atmosphere. This means that the air develops a particularly large amount of energy.
Such supercells are also often responsible for hail and can also develop into a small tornado. Powerful, so-called mesocyclonic tornadoes then form in ten to twenty percent of all supercells.
These localized low-pressure storms, like those seen in North Dakota Friday, are powered by what’s called the Coriolis force, which results from Earth’s rotation.
