Preliminary Application of Long-Range Lightning Location Network with Equivalent Propagation Velocity in China

Remote Sensing, 2022
The equivalent propagation method adopts a variable propagation velocity in lightning location, minimizing the location error caused by various factors in the long-range lightning location network. To verify the feasibility of this method, we establish a

Formation of Saturn's ring spokes by lightning-induced electron beams [PDF]

, 2006
Spokes are near-linear markings sometimes visible on Saturn's rings. They are widely accepted as being electrostatically-levitated sheets of similar to 0.6 micron-radius charged grains.
