Lightning Electric and Magnetic Fields
Characteristics of measured electric and magnetic fields generated by various lightning processes are reviewed. Ground flashes of both polarities and cloud flashes are considered. Examples of different types of field waveforms are given.
متن کاملExpressions for far electric fields produced at an arbitrary altitude by lightning return strokes
[1] Electromagnetic fields produced at high altitudes by return strokes in cloud-to-ground lightning are needed in studies of transient luminous events in the mesosphere. Such calculations require the use of a lightning return stroke model. Two of the widely used return stroke models are (1) the modified transmission line model with exponential decay (MTLE) of current with height and (2) the mo...
متن کاملElectric Field Pulse Bursts in Cloud-to-ground Lightning Discharges
Regular bursts of electric field radiation pulses produced by three multiple-stroke cloud-to-ground discharges recorded in 1991 at the NASA Kennedy Space Center are analyzed. The bursts are similar in the number of pulses per burst and inter-pulse intervals to the “multiple burst” component (so-called component H) of the standard lightning environment for the design and testing of aerospace veh...
متن کاملMesospheric Electric Field Transients due to Tropospheric Lightning Discharges
A physical picture and quantitative two-dimensional electromagnetic modeling of mesospheric electric field transients produced by cloud-to-ground (CG) lightning discharges with short duration currents (<0.5 ms) are presented. The range of applicability of existing quasi-electrostatic models of sprites and the physical conditions under which relatively weak CG lightning discharges (thundercloud ...
متن کاملCharacteristics of Lightning Discharges and Electric Structure of Thunderstorm
Progresses in the research on physical processes of lightning discharge and electric structure of thunderstorm in the last decade in China have been reviewed. By using the self-developed lightning detecting and locating techniques with high temporal and spatial resolution, the characteristics and parameters of lightning discharge in some representative areas in China have been obtained. Observa...
