  author={Yoshihiko Ohtsuki and H. Ofuruton},
DESPITE many experimental and theoretical studies, a widely accepted explanation of ball lightning has yet to be found. It is possible, however, that ball lightning is created by the interaction of different types of energy in the atmosphere1. Indeed, the production of a fireball by an electric discharge in an atmosphere containing dilute fuel gases such as propane has been reported2. We have also managed to produce several types of fireball by setting off electric discharges in an atmosphere… 
Relativistic-microwave theory of ball lightning
The theory suggests that ball lighting can be created in the laboratory or triggered during thunderstorms, and should be useful for lightning protection and aviation safety, as well as stimulate research interest in the relativistic regime of microwave physics.
Measurement of electromagnetic field near a fireball
Summary form only given, as follows. Kapitza (1955) proposed a theory of a ball lightning. He suggested that a ball lightning is formed at an antinode of the standing radio waves produced by
Nature of Fireballs Produced by Microwave Interference
A lot of people have been interested in ball lightning for over a hundred years (Barry, 1980). International symposia and workshops on ball lightning were held for the past few years. However,
Numerically investigation of electromagnetic field with fireball formation
Summary form only given. Kapitza proposed a theory of ball lightning (1995). He suggested that ball lightning is formed at regions where intensity of radio waves, produced by thunderstorms, become
Experimental conditions for ball lightning creation by using air gap discharge embedded in a microwave field
An experiment was carried out to reproduce ball lightning by using microwave radiation and electric discharge without a metal cavity. When the energy of the discharge was high, a plasma fireball was
Experimental investigation of large-volume PIA plasmas at atmospheric pressure
Large-volume atmospheric-pressure plasmas have been the subject of previous research as a laboratory simulation of ball lightning, but measurements of the plasma properties have been unavailable. The
Fireball ejection from a molten hot spot to air by localized microwaves.
The experimental observations of fireball ejection from silicate hot spots are referred to the Abrahamson-Dinniss theory, suggesting a mechanism for ball-lightning initiation in nature.
Self-similar magnetohydrodynamic model for direct current discharge fireball experiments
Ball lightning models and corresponding laboratory efforts in generating fireballs are briefly summarized to give an overview of the current status. In particular, emphasis is given to direct current

Ball lightning has been extensively observed in atmospheric air, usually in association with thunderstorms, by untrained observers who were not in a position to make careful observations. These
The present paper describes the interaction of the maser with the soliton, finally deriving the fundamental ball lightning (BL) equation for the linear heat diffusion case. This equation is a rough


Sustained, Localized, Pulsed-Microwave Discharge in Air
SEVERAL recent publications1–4 discuss possible methods whereby a localized gas discharge might be maintained by electromagnetic radiation. Recently a simple experiment to maintain an electrodeless

Experimental research on ball lightning
SummaryExperiments on producing ball lightning were made with discharge in flammable gas and/or aerosol. A long lifetime (2 s) ball lightning was observed in 2.7% ethane and 100 cm3 cotton fibers,
