通过对位于羊八井宇宙射线实验室（4300 m a.s. l）的ARGO-YBJ全覆盖空气阵雨阵列实验数据的分析，发现了雷暴期间二次宇宙射线通量与近地电场强度之间的相关性。已被发现强烈依赖于在15个雷暴过程中测量的电场的强度和极性。在负电场中（即加速负电荷向下），计数率随着电场强度的增加而增加。在正场中，速率随着场强度的增加而降低，直到场EFmin达到一定值（其值取决于事件的多重性），超过该值，速率开始增加。通过蒙特卡罗模拟，我们发现探测器上方几百米厚的大气层中存在一个电场，可以很好地描述这种特殊行为，该电场加速/减速了带相反电荷的二次簇射粒子，改变了能量超过探测器阈值的粒子数量。这些结果第一次对几十年来高空宇宙射线探测器在雷暴期间观测到的电子/正电子通量变化的起源给出了一致的解释。
A correlation between the secondary cosmic ray flux and the near-earth electric field intensity, measured during thunderstorms, has been found by analyzing the data of the ARGO-YBJ experiment, a full coverage air shower array located at the Yangbajing Cosmic Ray Laboratory (4300 m a. s. l., Tibet, China). The counting rates of showers with different particle multiplicities, have been found to be strongly dependent upon the intensity and polarity of the electric field measured during the course of 15 thunderstorms. In negative electric fields (i.e. accelerating negative charges downwards), the counting rates increase with increasing electric field strength. In positive fields, the rates decrease with field intensity until a certain value of the field EFmin (whose value depends on the event multiplicity), above which the rates begin increasing. By using Monte Carlo simulations, we found that this peculiar behavior can be well described by the presence of an electric field in a layer of thickness of a few hundred meters in the atmosphere above the detector, which accelerates/decelerates the secondary shower particles of opposite charge, modifying the number of particles with energy exceeding the detector threshold. These results, for the first time, give a consistent explanation for the origin of the variation of the electron/positron flux observed for decades by high altitude cosmic ray detectors during thunderstorms.
