Mesosphere-troposphere coupling due to sprites
Results from a new three-dimensional fractal model of sprites as well as recent experimental data on thundercloud charge moment changes associated with sprites indicate that ionized regions in sprites can sometimes reach thundercloud tops, creating favorable conditions for establishing a highly conducting link between the Earth’s surface and the lower ionosphere.
متن کاملOptical and VLF Imaging of Lightning-Ionosphere Interactions
This work addresses some of the key topics of space physics research recommended in the National Research Council 2003 report “A Decadal Research Strategy in Solar and Space Physics”, namely, the thunderstorm-driven electrodynamic coupling between the troposphere, mesosphere, lower ionosphere, and magnetosphere. Lightning-induced electron precipitation encompasses all of these regions, from atm...
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 کاملThe Stratosphere and its Coupling to the Troposphere and Beyond
The Stratosphere and its Coupling to the Troposphere and Beyond Synonyms Middle atmosphere Definition As illustrated in Figure 1, the Earth's atmosphere can be separated into distinct regions, or " spheres, " based on its vertical temperature structure. In the lowermost part of the atmosphere, the troposphere, the temperature declines steeply with height at an average rate of approximately 7 • ...
متن کاملStratosphere–Troposphere Coupling in the Southern Hemisphere
This study examines the temporal evolution of the tropospheric circulation following large-amplitude variations in the strength of the Southern Hemisphere (SH) stratospheric polar vortex in data from 1979 to 2001 and following the SH sudden stratospheric warming of 2002. In both cases, anomalies in the strength of the SH stratospheric polar vortex precede similarly signed anomalies in the tropo...
