How Eyewitnesses Describe Ball Lightning

Accounts of ball lightning vary significantly, but when we compile and filter these reports, a general description emerges. Typically, ball lightning appears as a luminous "fireball" that usually manifests during thunderstorms and hovers close to the ground. Most instances involve spheres measuring no more than half a meter in diameter, though there are anecdotal claims of much larger balls, measuring 2–3 meters. However, the credibility of these larger claims is often questioned. Observers report that ball lightning moves erratically, sometimes seemingly pursuing individuals or objects. The duration of its existence is typically short, lasting only seconds, although some reports suggest it can persist for several minutes.

Encounters with ball lightning can be perilous. Numerous accounts detail severe injuries or fatalities linked to contact with this phenomenon. A historical example includes Georg Richman, a prominent researcher of atmospheric electricity in St. Petersburg, who tragically lost his life due to ball lightning.

What Is the Scientific Consensus?

Currently, there is no widely accepted scientific explanation for ball lightning. This is largely because such phenomena rarely make their way into laboratories where scientists can observe and analyze them. Typically, only a handful of ball lightning events are reported each year.

Various theories attempt to clarify the nature of this enigmatic occurrence. Interestingly, some scientists even express skepticism regarding its existence, as portrayed by eyewitnesses.

Hypotheses and Theories Surrounding Ball Lightning

One of the earliest theories was proposed by the Russian scientist P. L. Kapitsa, who suggested that ball lightning is a form of standing electromagnetic wave. According to this hypothesis, electromagnetic oscillations occurring during thunderstorms can reflect off the Earth's surface, potentially creating conditions conducive to the formation of ionized plasma, which we term ball lightning.

The most compelling theory posits that ball lightning is a form of plasma created by the impact of regular lightning. This notion is supported by observations linking the appearance of ball lightning to instances of regular lightning strikes.

However, a challenge arises due to the tendency of positive and negative ions to recombine into neutral atoms, which typically occurs rapidly (in fractions of a second). Thus, it raises the question of how ball lightning can maintain its existence for extended periods. Recent insights suggest that water molecules (H2O)—composed of two hydrogen atoms and one oxygen atom—might play a crucial role. The negatively charged oxygen atom could attract positive ions, while the positively charged hydrogen atoms might draw in negative ions. This interaction could significantly slow down the recombination process, allowing ball lightning to persist for several seconds or longer.

Similar phenomena can be observed when ordinary salt dissolves in water, as the water molecules encapsulate sodium and chlorine ions.

Another intriguing hypothesis proposes that ball lightning may originate from evaporating soil particles. This theory gains some support from studies conducted by Chinese scientists, who managed to capture a few seconds of ball lightning on video. Spectral analysis of the glow revealed the presence of iron, calcium, silicon, and other soil constituents.
