Scientists have photographed “upwards lightning”, a rarely-seen phenomenon where electricity from storms flows into the upper atmosphere.

The photo was taken during last year’s Tropical Storm Cristobal.

Also known as “gigantic jets”, these events are just as powerful as cloud-to-ground lightning bolts.

The team from Duke University, also took radio measurements of the electrical charge.

Their work, published in Nature Geoscience, gives scientists a better understanding of this form of lightning.

Gigantic jets do not occur during every storm and scientists do not yet know what types of storm are conducive to their formation.
