[1] This study uses TRMM lightning and radar observations to study the fundamental relationship between precipitation ice mass and lightning flash density. The results indicate that the physical assumptions of precipitation-based charging and mixed phase precipitation development are robust and that on a global scale, the relationship between precipitation ice water path and lightning flash den...

Observational studies have reported solar magnetic modulation of terrestrial lightning on a range of time scales, from days to decades. The proposed mechanism is two-step: lightning rates vary with galactic cosmic ray (GCR) flux incident on Earth, either via changes in atmospheric conductivity and/or direct triggering of lightning. GCR flux is, in turn, primarily controlled by the heliospheric ...

The distribution of lightning current in the lightning protection system (LPS) and the electrical circuit of two test structures simulating residential buildings was experimentally studied at two research facilities in Florida and in Poland. In Florida, the experiments were conducted using rocket-triggered lightning, and in Poland a mobile current surge generator was employed. The soil in Flori...

Abstract. Satellite (Lightning Imaging Sensor) based lightning flash grid (0.5 x 0.5) data over the land mass areas of the Indian region covering between 8-30N for a period of 4 years (1998-2001) have been analyzed to examine their geographical, annual, interannual and diurnal distribution. An attempt has been made to obtain IC:CG ratio. Result of this study demonstrates that there exists latit...

The Los Alamos National Laboratory/Sandia National Laboratory FORTE satellite is described and its capabilities for global remote sensing of lightning in the radio regime are described. Some results from 7 years of successful operation are presented. A future global lightning monitoring mission, VGLASS, is described.

A triggered-lightning experiment and EMTP modeling of that experiment are used to study the responses of a twoconductor overhead power line to a direct lightning strike. The experiment was conducted at the International Center for Lightning Research and Testing (ICLRT) at Camp Blanding, FL. The lightning was artificially initiated (triggered) from a natural thundercloud using the rocket-and-wir...

Lightning and switching overvoltages are the main causes for faults in electrical networks. In the last decades, several different conventional methodologies have been used for the adjustment of the lightning performance of high voltage transmission lines, which are protected against lightning using overhead ground wires and surge arresters. The current paper proposes a new developed Artificial...

The study of the interaction of lightning electromagnetic fields with electrical systems and the design of appropriate protection strategies are generally based on statistical distributions of the lightning current measured at the channel base using either instrumented towers or artificial initiation of lightning using rockets. Recent studies based both on numerical modeling and experimental ob...

A computational study of the relationships linking lightning frequency and other x thundercloud parameters, Q. J. R. Meteorol. Soc., 121, 1525–1548 has been refined and extended, in an effort to provide a more realistic framework from which to examine computationŽ ally the relationships tha...

Cloud-to-ground (CG) lightning flash data collected by the lightning detection network installed at the Korean Meteorological Administration (KMA) have been used to study the urban effect on lightning activity over and around Seoul, the largest metropolitan city of South Korea, for the period of 1989–1999. Negative and positive flash density and the percentage of positive flashes have been calc...
