Short summary
Short summary
A terrestrial lightning event has been spectroscopically observed from the JUICE spacecraft during a flyby, maybe for the first time from space. Though not detected by ground sensors, JUICE confirmed neutral atomic oxygen and nitrogen emissions, with energies and temperatures consistent with average lightning. This observation is a benchmark for Jupiter, a primary JUICE target, where simultaneous hydrogen emissions in different wavelength ranges could be used to identify lightning.

We contribute to understanding differences in lightning flashes of opposite polarity by explaining distinct in-cloud processes after return strokes. Using data from multiple sensors, including individual Lightning Mapping Array stations, we reveal that positive flashes sustain strong high-frequency radiation due to the recharging of their in-cloud leader; this is in contrast to negative flashes, for which this activity declines rapidly.

Lightning and extreme weather can endanger people and technology. Despite advances in science, not all the factors that lead to the formation of thunderclouds, to their charging and to lightning ignition are known in detail. This paper shows that lightning frequency may, to some extent, be modulated by solar activity and solar wind. Namely, in the region of the South Atlantic Anomaly of the Earth's magnetic field, it correlates with the polarity and intensity of the solar wind.

Short summary
The 2014–2015 winter brought an enormous number of lightning strokes to northern Europe, about 4 times more than their long-term median over the last decade. This unusual production of lightning, concentrated above the ocean and along the western coastal areas, was probably due to a combination of large-scale climatic events like El Niño and the North Atlantic Oscillation, causing increased sea surface temperatures and updraft strengths, which acted as additional thundercloud-charging drivers.

We present the first-ever reported gamma-ray glows from a winter thunderstorm in continental Europe. Although two glows were detected at the same time, only one was ended by a discharge. Using advanced instruments such as the Ka-band vertically oriented Doppler radar and SEVAN detector, we gained new insights into the inner thunderstorm processes even in a cloud only 3 km in height.

This work studies powerful bursts of radiation, called Terrestrial Gamma Ray Flashes, which happen during thunderstorms. It explores the use of planes and weather balloons as platforms for radiation detectors to gather data about this phenomenon. Using computer simulations, it was found that balloons might work better for high-altitude storms, while planes could be useful for lower ones. Moreover, the influence of the Terrestrial Gamma Ray Flash strength and its altitude of origin was revealed.

Short summary
Storm activity is sometimes associated with the generation of ionizing radiation. Our motivation for performing this research was to understand its origin. Using measuring cars fitted with new instruments, it was found that the duration of lightning is longer than generally thought. In most cases, lightning occurs only inside the cloud; however, rarely, it is also visible outside the cloud. In such cases, the course of emission over time can be used to assume what it looks like inside the cloud.

Short summary
Gamma ray radiation related to thunderstorms was previously observed at the high-altitude mountain observatories or on the western coast of Japan, usually being terminated by lightning discharges. We show unusual observations of gamma rays at an altitude below 1000 m, coinciding with peculiar rapid variations in the vertical electric field, which are linked to inverted intracloud lightning discharges. This indicates that a strong, lower positive-charge region was present inside the thundercloud.
Gamma ray radiation related to thunderstorms was previously observed at the high-altitude...
