Direct observations of X-rays produced by upward positive lightning [PDF]

Scientific Reports
X-rays have been observed in natural downward cloud-to-ground lightning for over 20 years and in rocket-triggered lightning for slightly less. In both cases, this energetic radiation has been detected during the stepped and dart leader phases of downward

Upward negative leaders in positive triggered lightning: Stepping and branching in the initial stage

Geophysical Research Letters, 2017
By conducting comprehensive observation on the rarely triggered positive lightning flashes, two cases of upward negative leaders were quantitatively investigated with simultaneous data of current, optical, and electromagnetic field changes at fine time ...

Spatio‐Seasonal Risk Assessment of Upward Lightning at Tall Objects Using Meteorological Reanalysis Data

Earth and Space Science
This study investigates lightning at tall objects and evaluates the risk of upward lightning (UL) over the eastern Alps and its surrounding areas. While uncommon, UL poses a threat, especially to wind turbines, as the long‐duration current of UL can ...
