Studying Recorded lightning over Iraq for Period 1998-2011
This research studies distribution of thunderstorm in Iraq for the period (1998-2011), the result showed that the largest regions which had been hit by lightning stroke were between latitude (35-36◦)E and longitude (45-46◦)N, and April was the most ...

The electric field of overhead thunderclouds [PDF]
Abstract In a previous paper* I drew attention to the fact that, owing to the peculiar geographical position of Bombay, almost all the “ heat ” thunderstorms which form during the pre-monsoon and the post-monsoon periods over the hills to the east of the Colaba Observatory, between the sea coast and the Western Ghats, develop a ...

The strong very high frequency (VHF) radiation from compact intra‐cloud discharges (CIDs) is attributed to streamers. An analytical model, taking altitude and applied electric field as input, is developed for effective representation of current for a ...

Stepped Leader Progression and Speed Evolution in a Thunderstorm: Theoretical Model
This paper presents a theoretical model to describe the progression of leading (falling) lightnings in storms (stepped leaders). Stepped leaders move down from the thundercloud base to the encounter point with an upward streamer.

Post-return stroke VHF electromagnetic activity in north-western Mediterranean cloud-to-ground lightning flashes [PDF]
We investigate properties of the electromagnetic activity following the first lightning return stroke (RS), using concurrent observations from the SLAVIA (Shielded Loop Antenna with a Versatile Integrated Amplifier) sensor, the SAETTA (Suivi de l ...

Rapid evolution of energetic lightning strokes in Mediterranean winter storms
The occurrence of winter lightning concentrates in a few specific regions in the world, including the Mediterranean, where electromagnetic signatures of this interesting dangerous phenomenon have not yet been studied in detail. We investigate the initial
