Microspherules formed by lightning strikes
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Air Quality Penalty in Southeast Asia Driven by AMOC Slowdown
Abstract The Atlantic Meridional Overturning Circulation (AMOC) regulates Earth's climate by redistributing heat and freshwater across the Atlantic Ocean. While accelerating Arctic melt is expected to weaken the AMOC, its implications for atmospheric composition remain poorly understood.

Detecting Thunderstorm‐Related High‐Energy Phenomena in Weak Signals
Abstract Gamma‐ray glows (GRGs) are high‐energy events associated with thunderstorms, characterized by an enhancement of the high‐energy background radiation lasting from a few seconds to several minutes. They are typically detected near their sources by balloons, aircraft, mountain‐based observatories, or at sea level in regions where thunderstorms ...

Correlated measurements of UHF radar signatures, RF radiation and electric field changes from lightning [PDF]
During Storm Hazards - 82, simultaneous measurements are made of radar echoes, fast and slow field changes and RF radiation from lightning. Radio frequency radiation and radar echoes are also obtained during periods when the research aircraft is struck ...

Helicopter Triggered Lightning in Norway
Helicopters are sometimes hit by lightning when flying offshore along the coast of Norway. Often, the helicopter’s presence is what triggers the lightning strike, and this phenomenon is called Helicopter Triggered Lightning (HTL). These lightning strikes present both an economic and a safety risk to offshore operators.

The effects of the exhaust plume on the lightning triggering conditions for launch vehicles [PDF]
Apollo 12 and Atlas Centaur 67 are two launch vehicles that have experienced triggered lightning strikes. Serious consequences resulted from the events; in the case of Atlas Centaur 67, the vehicle and the payload were lost. These events indicate that it
