Initial Geostationary Lightning Mapper Observations [PDF]

Geophysical Research Letters, 2019
AbstractThe Geostationary Lightning Mapper (GLM) continuously observes lightning throughout a near‐hemispheric field of view, capturing spatiotemporal variability on unprecedented scales. This study documents GLM lightning distributions during the initial 9 months in the operational Geostationary Operational Environmental Satellite‐East position ...

Effect of Mountain Terrain near Lightning Channels on Electric Fields at Sprite Halos Initiation Region

Atmosphere
The electric fields generated by lightning discharges propagate upward and couple with the lower ionosphere, triggering various mesospheric optical emissions.

Polarimetric radar characteristics of lightning initiation and propagating channels [PDF]

Atmospheric Measurement Techniques, 2019
In this paper we present an analysis of a large dataset of lightning and polarimetric weather radar data collected in the course of a lightning measurement campaign that took place in the summer of 2017 in the area surrounding Säntis, in the northeastern

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.

Influences of Building Slope Angle on the Initiation of Stable Upward Leader

应用气象学报
The slope angle (or top angle) of the building significantly influences the formation of upward leader. To simulate the lightning strike process on tall and sloping building using three-dimensional variable grid leader model, the influence of slope angle

Advances of Observation and Study on Tall-object Lightning in Guangzhou over the Last Decade

应用气象学报, 2020
Comparing to the ground or low-object, tall-object is more likely to reach the threshold for the initiation of leader on its top due to the distortion and enhancement of electric field, therefore tall-object is not only easier to get struck by downward ...

On the influence of corona on lightning-induced overvoltages

, 2010
An experimentally inferred charge-voltage (Q-V) diagram used to macroscopically model the corona phenomenon is adopted for the calculation of the lightning-induced transients in presence of corona. The paper aim at presenting the calculation procedure as
