Nature: When lightning strikes — the LOFAR radio telescope is watching closely

(Karlsruher Institut für Technologie (KIT) ) It is still unclear what exactly happens when lightning develops. Based on high-resolution data of the LOFAR radio telescope, an international team of researchers has now discovered needle-shaped structures. They might help to explain why lightning does not always discharge at once, as was thought for a long time, but can strike several times within seconds. Essential foundations for measuring lightning with the world’s largest antenna array were laid at KIT.

Why lightning often strikes twice

Scientists have used the LOFAR radio telescope to study the development of lightning flashes in unprecedented detail. Their work reveals that the negative charges inside a thundercloud are not discharged all in a single flash, but are in part stored alongside the leader channel at Interruptions, inside structures which the researchers have called needles. This may cause a repeated discharge to the ground.
