Lightning Activity Observed by the FengYun-4A Lightning Mapping Imager [PDF]
Remote Sensing, 2021 The Lightning Mapping Imager (LMI) onboard the geostationary meteorological satelliteFengYun-4A (FY-4A) detects both intra-cloud (IC) and cloud-to-ground (CG) lightning continuously during daytime and nighttime. This study examined, for the first time, the optical characteristics and distribution of the “Event,” “Group,” and “Flash” observed by the LMI

Seasonal Variability of Lightning Activity in Yakutia in 2009–2019
Atmosphere, 2020 The instrumental continuous monitoring of lightning activity in Yakutia has been carried by the lightning direction finder since the 2000s. Devices for detection of sferic (very low frequency radio pulses emitted by lightning discharges) in Yakutia were ...

Triggered Calcium Lightning Programs Cochlear Development. [PDF]
Exploration (Beijing)Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

On the Initiation of Upward Negative Lightning by Nearby Lightning Activity: An Analytical Approach [PDF]
Journal of Geophysical Research: Atmospheres, 2021 AbstractUpward lightning occurs generally from tall structures. The mechanism of the initiation of upward lightning is not yet fully understood. Upward lightning can be classified into two categories based on either the absence or the presence of other lightning activity prior to the upward flash.
