These days, violent thunderstorms are once again moving across Austria - including so-called supercells. An expert from Geosphere Austria told Krone+ what their formation has to do with screws and football throws, how to recognize them and why they are dangerous.

Cyclone alert in Istria, dramatic flooding in southern Germany with fatalities, land under water in parts of Austria too. And, unfortunately, that's not the end of the storms - (more) supercells are threatening to sweep over us these days. Not unusual per se: "Around ten percent of all thunderstorms are supercells," says climate researcher Georg Pistotnik from Geosphere (formerly ZAMG), immediately explaining what these threatening weather phenomena are all about.
