Polarity Asymmetries in Rocket‐Triggered Lightning

Geophysical Research Letters, 2023
The dissonant development of positive and negative lightning leaders is a central question in atmospheric electricity. It is also the likely root cause of other reported asymmetries between positive and negative lightning flashes, including the ones ...

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
