NO signatures from lightning flashes
In situ measurements of cloud properties, NO, and other trace gases were made in active thunderstorms by two research aircraft. Concurrent measurements from a three-dimensional (3-D) VHF interferometer and the 2-D National Lightning Detection Network were used to determine lightning frequency and location. The CHILL Doppler radar and the NOAA-WP-3D Orion X band Dopper radar were also used to me...
متن کاملCharacteristics of lightning flashes over the Indian region
Abstract. Satellite (Lightning Imaging Sensor) based lightning flash grid (0.5 x 0.5) data over the land mass areas of the Indian region covering between 8-30N for a period of 4 years (1998-2001) have been analyzed to examine their geographical, annual, interannual and diurnal distribution. An attempt has been made to obtain IC:CG ratio. Result of this study demonstrates that there exists latit...
متن کاملAn Analysis of the Lightning Jump Algorithm Using Geostationary Lightning Mapper Flashes
This project aims to implement the two-sigma lightning jump algorithm (LJA) developed using Lightning Mapping Arrays (LMAs), with GOES-16 Geostationary Lightning Mapper (GLM) flashes, evaluate its performance, and identify any needed adjustments to the algorithm to optimize operational skill. The GLM is projected to have lower detection efficiency (DE) (7090 percent) than operational LMAs (95-9...
متن کاملLightning leader altitude progression in terrestrial gamma-ray flashes
Radio emissions continue to provide insight into the production of terrestrial gamma ray flashes (TGFs) by thunderstorms, including the critical question of the conditions under which they are generated. We have identified several TGF-associated lightning radio emissions in which the altitudes of in-cloud lightning leader pulses that precede and follow the TGF can be measured. We combine these ...
متن کاملMicrowave radio emissions of negative cloud-to-ground lightning flashes
Article history: Received 6 August 2012 Received in revised form 31 January 2013 Accepted 6 February 2013 We report preliminary results of a new observational study of microwave-frequency electromagnetic radiation that is emitted by lightning discharge processes. Radiation was observed with a ceramic patch antenna and a digital radio receiver tuned to a center frequency of 1.63 GHz and a bandwi...
