First Observations and Characteristics of Positive Upward Illumination Strokes

Geophysical Research Letters
Upward Illumination (UI) strokes are a subtype of cloud‐to‐ground (CG) return strokes characterized by two concurrent branches striking the ground a few milliseconds apart.

Effective Height of Mountaintop Towers Revisited: Simulation-Based Assessment for Self-Initiated Upward Lightning

Atmosphere
Mountaintop towers are highly exposed to self-initiated upward lightning flashes. Accurate estimation of their effective height—the equivalent flat-ground height yielding the same lightning exposure—is essential for reliable exposure assessment, for ...

Launch pad lightning protection effectiveness [PDF]

Using the striking distance theory that lightning leaders will strike the nearest grounded point on their last jump to earth corresponding to the striking distance, the probability of striking a point on a structure in the presence of other points can be

Upgraded Low-Frequency 3D Lightning Mapping System in North China and Observations on Lightning Initiation Processes

Remote Sensing
The three-dimensional (3D) low-frequency lightning mapping system (LF-LMS) in north China has been updated. The lightning electric field derivative (dE/dt) sensor and continuous acquisition mode has been newly designed to ensure a capability of entire ...

Summary of Almost 20 Years of Storm Overflight Electric Field, Conductivity, Flash Rate, and Current Statistics [PDF]

, 2011
We present total conduction (Wilson) currents for more than 1000 high-altitude aircraft overflights of electrified clouds acquired over nearly two decades. The overflights include a wide geographical sample of storms over land and ocean, with and without
