“…Cloud‐to‐ground lightning activity data have been obtained from the Colombian Total Lightning Detection Network, operated by the Keraunos Colombia since 2011 (Aranguren et al, ). This network is composed of nineteen low frequency (VLF/LF) sensors of LINET type (Betz et al, ) with baselines between 90 and 140 km.…”

“…This network is composed of nineteen low frequency (VLF/LF) sensors of LINET type (Betz et al, ) with baselines between 90 and 140 km. Performance of this network can be found in Aranguren et al (). It is important to mention that in this study we only consider could‐to‐ground (CG) strokes with peak current amplitudes greater than 10 kA as suggested by Cummins et al ().…”

Charge Structure of Two Tropical Thunderstorms in Colombia

et al. 2019

Charge structure derived from lightning leader development of tropical thunderstorms comprising equatorial latitudes of less than ±10° has not been investigated yet. In this work, using a lightning mapping array installed in northern Colombia, the charge structure, lightning leader initiations, and the cloud‐to‐ground strokes rates of two thunderstorms have been analyzed. Additionally, radar information is also included. The identification of the charge regions has been obtained by analyzing the propagation of lightning leader developments. Flashes initiate between 4‐ and 15‐km altitude. High initiation rates are different in the two storms. In one case the high rates are found between 8 and 13 km. In the other case, the initiation heights are found between 10 and 15 km. The storms show typical tripolar charge structure where the upper positive charge is present at 10 to ~15 km, the midlevel negative charge is found between 6 and 9 km, and the lower positive charge between 4 and 6 km altitude. Intracloud lightning flashes with inverted polarity have been identified for short period. In other periods, screening layer flashes have been detected at 14–15 km. The overall results show that the charge structures in the two Colombian storms are similar to the structures reported in North Central Florida, but with the significant difference that the flash initiation altitudes are 2 km higher in Colombia. The vertical configuration of the charge regions and the leader development of these thunderstorms may help explain the occurrence of terrestrial gamma‐ray flashes in tropical thunderstorms.

“…Cloud-to-ground (CG) lightning locations and peak currents are provided by the Keraunos SAS LINET type lightning network in Colombia (Aranguren et al, 2017;Betz et al, 2009) and by the World-Wide Lightning Location Network (WWLLN, e.g., Rodger et al, 2006). Additionally, extremely low frequency (ELF) magnetic fields (<0.01-300 Hz) measured by the UPC Schumann resonance station in Cape Verde (16.73°N, 22.93°W) are used to identify the presence of continuing currents for those transient events superimposed over the continuous Schumann resonance background (e.g., Boccippio et al, 1995;Burke & Jones, 1996;Huang et al, 1999).…”

In the near future, much of the Earth's lightning activity will be continuously monitored from space by lightning imagers placed in geostationary orbit. These new satellite-based instruments open a new era of weather monitoring and research into the role of thunderstorm processes in the dynamics of the atmosphere and in climate change. The Geostationary Lightning Mapper (GLM) on the first of the Geostationary Operational Environmental Satellite GOES-R Series (GOES-16 at 75.2 W) is the first lightning detector in geostationary orbit (Goodman et al., 2013; Rudlosky et al., 2019a, 2019b). GLM is based on its predecessors, the Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS) Boccippio et al., 2002, Christian et al., 1989). In China, the Lightning Mapping Imager (LMI) on the Feng-Yun4 is detecting lightning in Asia (Yang et al., 2017) and in the near future, Europe and Africa will be continuously monitored by the Lightning Imager (LI) on the Meteosat Third Generation satellites (MTG) (Stuhlmann et al., 2005). All of these systems, new to the geostationary orbit, use optical imagers at the narrow spectral line at the 777.4 nm infrared emission of atomic oxygen that is associated with hot lightning channels (e.g., Soler et al., 2020). The Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station (ISS) consists of a suite of optical instruments and X-ray and gamma-ray detectors for investigating lightning, Transient Luminous Events (TLEs) and Terrestrial Gamma-ray Flashes (TGFs) (e.g., Chanrion et al., 2019; Neubert et al., 2019). ASIM is equipped with three photometers at 180-230 nm, 337.0 and 777.4 nm spectral bands plus two one-megapixel cameras at 337.0 and 777.4 nm. The objective of the 337.0 nm (blue) and 777.4 nm

The natural phenomenon of thunderstorm activity is one of many causes of a forest fire. Thunderstorms cause especially intensive fire danger situations within remote areas and highlands. As a rule, a cloud-to-ground lightning discharge is the fire source. The present study is based on the research results of electrical overloads in supply networks. Physical and mathematical formulation and numerical solution for the problem of a coniferous tree (pine) ignited by a cloud-to-ground lightning discharge are presented. The problem is considered in a cylindrical coordinate system in two-dimensional formulation. The features of current passage and heat transfer taking into account the reactive wood localization are investigated. The Joule-Lenz’s law is used to calculate heat production in a tree trunk. Parametric analysis has been conducted and tree trunk ignition conditions have been determined in a typical range for the influencing parameters of negative and positive discharges.
