We present measurements of radio emission from cosmic ray air showers that took place during thunderstorms. The intensity and polarization patterns of these air showers are radically different from those measured during fair-weather conditions. With the use of a simple two-layer model for the atmospheric electric field, these patterns can be well reproduced by state-of-the-art simulation codes. This in turn provides a novel way to study atmospheric electric fields.
我们展示了对雷暴期间发生的宇宙射线空气簇射产生的射电辐射的测量结果。这些空气簇射的强度和极化模式与在晴朗天气条件下测量的结果截然不同。利用一个简单的两层大气电场模型，这些模式可以被先进的模拟代码很好地再现。这反过来提供了一种研究大气电场的新方法。
