The Effects of Thunderstorm Static and Quasi-Static Electric Fields on the Lower Ionosphere
Salem, Mohammad A. (2017-05)Thunderstorms and their lightning discharges are of great interest to many areas of geophysics and atmospheric electricity. A thunderstorm is an electric generator; it can produce both electrostatic and quasi-electrostatic ... -
Initiation of Streamers from Thundercloud Hydrometeors and Implications to Lightning Initiation
Sadighi, Samaneh (2015-05)Electric field values measured inside thunderclouds have consistently been reported to be up to an order of magnitude lower than the value required for the conventional electrical breakdown of air. This result has made ... -
Relativistic Runaway Electron Avalanches Inside the High Field Regions of Thunderclouds
Cramer, Eric Scott (2015-05)In this dissertation, simplified equations describing the transport and energy spectrum of runaway electrons are derived from the basic kinematics of the continuity equations. These equations are useful in modeling the ... -
Remote Sensing, Modeling, and Spectroscopic Studies of Gigantic Jets and Lightning Leaders
Boggs, Levi (2019-12)This dissertation focuses on four interrelated investigations with the ultimate goal of better understanding electrical phenomena in the lower and upper atmosphere. The four investigations utilized observations and data ... -
Sprite Streamer Formation and Propagation: Theory and Observations
Kosar, Burcu (2015-05)Sprites are finely-structured, large scale electrical discharges typically initiated near the lower boundary of the ionosphere at 70-85 km altitudes [Pasko, 2010; Ebert et al., 2010; Pasko et al., 2011, 2013; Liu, 2014; ... -
Theoretical and Experimental Investigations of the Electromagnetic Fields and Energetic Particles Associated with Thunderstorms and Lightning
Arabshahi, Shahab (2015-05)Despite more than 250 years after Benjamin Franklin’s kite experiment, lightning is still one of the mysteries of nature. We still do not understand how lightning works at the most basic level. Traditionally, lightning ...
