Ball lightning caused by oxidation of nanoparticle networks from normal lightning strikes on soil

  title={Ball lightning caused by oxidation of nanoparticle networks from normal lightning strikes on soil},
  author={John Abrahamson and James Dinniss},
Observations of ball lightning have been reported for centuries, but the origin of this phenomenon remains an enigma. The ‘average’ ball lightning appears as a sphere with a diameter of 300 mm, a lifetime of about 10 s, and a luminosity similar to a 100-W lamp. It floats freely in the air, and ends either in an explosion, or by simply fading from view. It almost invariably occurs during stormy weather. Several energy sources have been proposed to explain the light, but none of these models has…

This basic model of networked nanoparticles is detailed further, and extended to lightning strikes on metal structures, and also to the action of other storm–related discharges or man–made discharges.

The failure to contain plasmas electrochemically for more than a few seconds probably reflects the inability to balance (or even measure) the various fields which govern a ball's stability.

Ball Lightning–Aerosol Electrochemical Power Source or A Cloud of Batteries

Despite numerous attempts, an adequate theoretical and experimental simulation of ball lightning still remains incomplete. According to the model proposed here, the processes of electrochemical

Birth of ball lightning

[1] Many observations of ball lightning report a ball of light, about 10 cm in diameter, moving at about walking speed, lasting up to 20 s and frequently existing inside of houses and even

The Missing Science of Ball Lightning

One of the main problems in understanding ball lightning is that its properties, taken together, seem to be inconsistent with the laws of physics. This long-standing problem is completely eliminated

Ball lightning: elusive behaviour depending upon proton conductivity

A simple model of BL is presented, capable of explaining many of its observed properties, and it is suggested that the BL is a negatively charged spherical object consisting of a shell of oriented dipolar water molecules with low electronic conductivity in the radial direction and high proton conductivities in the tangential direction of the inner region of the shell.

This paper discusses three issues related to lightning. The first is to provide a quantitative physical explanation of the lightning stepped leader, whereby breakdown from a cloud to the ground

Further insight into the nature of ball-lightning-like atmospheric pressure plasmoids.

Results indicate that the lifetime and size of the plasmoid slightly increase as the pH of isoohmic electrolyte solutions deviate from neutrality, and schlieren images revealed a single, sharp density gradient at the boundary layer of the top and sides of the expanding ball-shaped plasmoids.

Toward a theory of ball lightning

It is postulated that ball lightning is initiated by a lightning stroke that forms a large sphere of heated material. The following models are considered: (1) cooling spheres of air; (2) cooling

The main characteristics of ball lightning are well established. They include its general appearance (shape, size range, brightness, etc.), its peculiar motion and, less satisfactorily, its energy

Lightning Strike Fusion: Extreme Reduction and Metal-Silicate Liquid Immiscibility

Thermodynamic calculations indicate that temperatures in excess of 2000 K and reducing conditions approaching those of the SiO2-Si buffer were needed to form the coexisting metallic and silicate liquids.

A Curious Phenomenon shown by Highly Charged Aerosols.

In the course of investigations on the electrification of aerosols, a curious phenomenon was noticed. The aerosols were volatilised in a glass chamber of about four cubic metres capacity. During the

The thermal‐oxidation kinetics of silicon are examined in detail. Based on a simple model of oxidation which takes into account the reactions occurring at the two boundaries of the oxide layer as

Analytical relationship for the oxidation of silicon in dry oxygen in the thin‐film regime

The oxidation of silicon in dry oxgen is characterized by an initial stage where the growth rate is larger than predicted by the Deal–Grove linear‐parabolic general oxidation relationship. This
