The Impulsive Nature of Lightning Initiation [PDF]
, 2021 <p>We report results from imaging the initiation region of lightning via 3D interferometric beamforming on data collected by the Netherlands-based core of the Low Frequency Array of Antennas (LOFAR). LOFAR achieves 1 nanosecond timing accuracy and meter-scale spatial precision in lightning imaging on pulses observed in the 30-80 MHz band ...

Characteristics of Regions with High-Density Initiation of Flashes in Mesoscale Convective Systems
Remote Sensing, 2022 To investigate the characteristics of regions exhibiting multiple lightning initiations within a finite volume and a short time, the lightning location data obtained from the convective regions of 14 mesoscale convective systems were analyzed in ...

Lightning at Jupiter pulsates with a similar rhythm as in-cloud lightning at Earth
Nature Communications, 2023 Our knowledge about the fine structure of lightning processes at Jupiter was substantially limited by the time resolution of previous measurements. Recent observations of the Juno mission revealed electromagnetic signals of Jovian rapid whistlers at a ...

Numerical simulation of the effect of atmospheric condition on the lightning strike for wind turbine
Frontiers in Earth Science, 2023 The risk of lightning exposure increases as wind turbine size increases, and lightning accidents have grown up to be a severe threat to wind turbines. The present paper focuses on the influence of the changes in atmospheric conditions around the rotating

Initial stage in lightning initiated from tall objects and in rocket‐triggered lightning [PDF]
Journal of Geophysical Research: Atmospheres, 2005 We examine the characteristics of the initial stage (IS) in object‐initiated lightning derived from current measurements on the Gaisberg tower (100 m, Austria), the Peissenberg tower (160 m, Germany), and the Fukui chimney (200 m, Japan) and their counterparts in rocket‐triggered lightning in Florida.

A pan-Alpine climatology of lightning and convective initiation
Monthly Weather Review, 2022 <p>A new lightning-flash and convective initiation climatology is developed over the Alpine area, one of the hotspots for lightning activity in Europe. The climatology uses cloud-to-ground (CG) data from the European Cooperation for LIghtning Detection (EUCLID) network, occurring from 2005 to 2019.
