Triangulation of sprites, associated halos and their possible relation to causative lightning and micrometeors
Sprite halos were recently identified as an impulsive but spatially diffuse phenomenon that sometimes occurs just prior to, but distinct from, sprites. The lack of discernible spatial structure andExpand
Sprites and possible mesospheric effects
Images of sprites have been recorded at 1 ms resolution revealing several new sprite properties. Sprites appear to occur in a highly structured mesosphere, and we suggest that the cause of some ofExpand
Statistical analysis of space-time relationships between sprites and lightning
Abstract We present a detailed statistical analysis of the association of 40 sprite events with lightning from the parent thunderstorm. Both temporal and spatial criteria were used to identify theExpand
Simultaneous Observations of Mesospheric Gravity Waves and Sprites Generated by a Midwestern Thunderstorm
from a central excitation region directly above the storm. During the initial stages of the storm outwardly expanding waves possessed a period of � ≈10 min and wavelength � ≈50 km. Over a 1 hExpand
Convection: the likely source of the medium-scale gravity waves observed in the OH airglow layer near Brasilia, Brazil, during the SpreadFEx campaign
Abstract. Six medium-scale gravity waves (GWs) with horizontal wavelengths of λH=60–160 km were detected on four nights by Taylor et al. (2009) in the OH airglow layer near Brasilia, at 15° S, 47° W,Expand
Characteristics of mesospheric gravity waves near the magnetic equator, Brazil, during the SpreadFEx campaign
As part of the SpreadFEx campaign, coordi- nated optical and radio measurements were made from Brazil to investigate the occurrence and properties of equatorial Spread F, and to characterize theExpand
Dynamical relationship of infrared cloudtop temperatures with occurrence rates of cloud‐to‐ground lightning and sprites
[1] We correlated cloudtop temperatures obtained from GOES-8 infrared images, lightning data from the National Lightning Detection Network, and triangulated nadir positions of sprites from a 22 JulyExpand
Simultaneous observations of equatorial F-region plasma depletions over Brazil during the Spread-F Experiment (SpreadFEx)
From September to November 2005, the NASA Living with a Star program supported the Spread-F Experi- ment campaign (SpreadFEx) in Brazil to study the effects of convectively generated gravity waves onExpand
Consequences of the application of the streamer fluid model to the study of the sprite inception mechanism
Abstract We present the results of a streamer-fluid model used to investigate the electrodynamical coupling between the troposphere and upper atmosphere due to the penetration of lightning electricExpand
Characteristics of sprite and gravity wave convective sources present in satellite IR images during the SpreadFEx 2005 in Brazil
We developed a technique to identify and esti- mate the size, intensity, and Tropopause overshoot of thun- derstorm convective cores expected to be significant sources of gravity waves. The work wasExpand
