Red sprites: Lightning as a fractal antenna
نویسنده
چکیده
A new and improved model of red sprites is presented. Emphasis is placed in accounting for the puzzling observation of the spatial structure in the red sprite's optical emissions. The model relies upon a horizontal fractal lightning discharge, which generates the EMPs that excites the optical emissions in the lower ionosphere. It is shown that the fractal model may account for the observed sprite's spatJolly structured optical pattern, while reducing the typical charge threshold to approximately 100 C.

متن کاملModel of red sprites due to intracloud fractal lightning discharges
A new and improved model of red sprites is presented. Emphasis is placed on accounting for the puzzling observation of the spatial structure in the exnissions. The model relies on the electromagnetic pulse (EMP) fields created by a horizontal lightning discharge and includes the observed fractal structure of such discharges in the computation of the EMP power density. It, is shown that the mode...
متن کاملFractal structure of sprites
A large scale model of sprites based on a phenomenological probabilistic approach to modeling of streamer corona discharges is developed. The model utilizes the experimentally documented macroscopic properties of positive and negative streamer corona in air and allows a realistic determination of the propagation of multiple breakdown branches in a self-consistent electric field. The model resul...
متن کاملA study of the possibility of sprites in the atmospheres of other planets
[1] Sprites are a spectacular type of transient luminous events which occur above thunderstorms immediately after lightning. They have shapes of giant jellyfish, carrots, or columns and last tens of milliseconds. In Earth’s atmosphere, sprites mostly emit in red and blue wavelengths from excited N2 and N2 + and span a vertical range between 50 and 90 km above the surface. The emission spectra, ...
متن کاملSprites triggered by negative lightning discharges
High altitude air breakdown, manifested as “red sprites,” is reported in close association with negative cloudto-ground lightning (−CG) on at least two occasions above an unusual storm on August 29, 1998. Data from high speed photometry, low-light-level video, and receivers of lightning electromagnetic signatures in the frequency range 10 Hz to 20 kHz are used to establish the association and i...
