传统放电理论认为，当电场接近每公尺 300 万伏特（约 3 MV/m）时，空气会击穿，电子雪崩加热空气形成可见等离子通道。然而在实际风暴测量中，典型电场仅为该临界值约十分之一，最强观测值也只有约三分之一。Michael Stock 指出这一差距，认为要么存在瞬时局部放大，要么另一种机制能绕过普通击穿。导电锐利冰雹粒子（hydrometeors）假说曾认为锐利冰片可提供帮助：1960–1970 年代，火箭拖线可触发放电，理论上估计可带来约 10 倍增强。随后的卫星时代影像却显示，风暴结构很少具有足够的尖锐度。
1994 年卫星在雷云上方探测到伽玛射线，进一步挑战了旧模型。Dwyer 借鉴 C.T.R. Wilson 与 Aleksandr Gurevich 的思想：一个相对论性「奔逸」电子可在数百到数千公尺尺度上雪崩，并由单一种子电子产生约十万个电子。当这些电子辐射时，伽玛光子可形成电子-正电子对；正电子可反向传播并种下新的雪崩，形成回授链，快速放大量子数和电场，正如 Dwyer 比喻的麦克风与扬声器回授。模拟显示此机制可将电场提升到可雷击条件并再现伽玛射线辐射，但研究者仍分歧其是否能完全解释所有雷电起始。
Lightning research has shifted from purely classical explanations toward high-energy physics after techniques used for cosmic explosions were turned on storms. Joseph Dwyer, who moved from studying solar flares with NASA’s WIND satellite to chasing lightning in Florida, says the emerging model links cloud flashes to processes usually associated with supernovas, black holes, and particle colliders. Even with centuries of inquiry using kites, balloons, and rockets, the basic initiation problem persists, while NASA data show more than 2,000 thunderstorms globally at any moment. This indicates the question is not rare: the mechanism for starting a strike remains a central unsolved issue across ordinary weather.
Classical discharge theory says air breaks down near 3 million volts per meter (about 3 MV/m), where electron avalanches heat air into a visible plasma channel. In actual storm measurements, however, typical electric fields are about one-tenth of that critical value, and the strongest observed fields are only about one-third of threshold. Michael Stock notes this mismatch and argues that either transient local amplification must occur or another mechanism must bypass ordinary breakdown. The hydrometeor-point hypothesis claimed pointed ice shards could help: in the 1960s–70s, rockets with trailing wires triggered discharges, and theory estimated a 10× boost from conductive sharp particles. Subsequent satellite-era imaging, though, suggests storm structures rarely produce the necessary tip sharpness.
Satellite detections of gamma rays over thunderclouds in 1994 further challenged the old picture. Dwyer used ideas from C.T.R. Wilson and Aleksandr Gurevich: a relativistic runaway electron can avalanche across hundreds to thousands of meters and generate roughly 100,000 electrons from one seed. When those electrons radiate, gamma photons can produce electron-positron pairs; positrons can reverse direction and seed fresh avalanches, creating a feedback chain that rapidly amplifies both particle number and electric field, as Dwyer likens to microphone-and-speaker feedback. Simulations show this can raise fields to lightning conditions and reproduce gamma-ray emissions, yet researchers remain divided on whether it fully explains all lightning starts.
