Abstract. Lightning is the major cause of natural ignition wildfires worldwide and produces largest in some regions. strokes produce about 5 % forest fires Mediterranean Basin are one most important precursors during summer. Lightning-ignited significant emissions aerosols, black carbon, trace gases, such as CO, SO2, CH4, O3, affecting air quality. Characterization meteorological cloud conditio...

Public key quantum money can be seen as a version of the quantum no-cloning theorem that holds even when the quantum states can be verified by the adversary. In this work, investigate quantum lightning, a formalization of “collision-free quantum money” defined by Lutomirski et al. [ICS’10], where no-cloning holds even when the adversary herself generates the quantum state to be cloned. We then ...

-Lightning protection air terminals are placed on structures and other grounded objects with the purpose of capturing the lightning stroke. A well estimation of the lateral protection distance is crucial in predicting the protection area of the lightning rod. This paper focus on a 3-D numerical modelling of lightning attachment based on physical phenomena leading to the formation and the develo...

Triggered-lightning properties, including dart-leader charge density, return-stroke propagation speed, dart-leader electric potential, dart-leader propagation speed, and dart-leader current, inferred from return-stroke current and very close electric field measurements, are presented. Although most of the estimates are based on relatively crude models, they are all generally in good agreement w...

Red Sprites: Lightning as a Fractal Antenna J. A. Valdivia 1, G. Milikh 2, and K. Papadopoulos 1;2 Dept. of Physics1, Dept. of Astronomy2, Univ. of Maryland, College Park, MD 20742 Abstract A new and improved model of the red sprites is presented. Emphasis is placed in accounting for the puzzling observation of small scale structure in the emissions. The model relies in a horizontal lightning d...

[1] We consider the use of lumped voltage and current sources in engineering lightning return stroke models with emphasis on those including a tall strike object. If the model is to be used for computing remote electric and magnetic fields, we suggest a representation of the lightning channel as a transmission line energized by a lumped voltage source, with the voltage magnitude being expressed...

[1] The accepted mechanism for whistler generation implicitly assumes that the causative lightning stroke occurs within reasonable proximity to the conjugate foot point of the guiding magnetic field line and that nighttime whistlers are prevalent because of low transionospheric attenuation. However, these assumptions are not necessarily valid. In this study we consider whistler observations fro...

Thirty-nine thunderstorms are examined using multiple-Doppler, polarimetric and total lightning observations to understand the role of mixed phase kinematics and microphysics in the development of lightning jumps. This sample size is larger than those of previous studies on this topic. The principal result of this study is that lightning jumps are a result of mixed phase updraft intensification...

Lightning flash activities on the central Tibetan Plateau have been studied by using the Lightning Imaging Sensor (LIS) database from 1998 to 2002. The lightning activity shows a clear diurnal variation on the central Plateau. The lightning discharge is weaker on the Plateau than in other low-altitude continental regions because of the lower convective available poential energy (CAPE) on the Pl...

Accurate estimates of tree mortality are essential for the development of mechanistic forest dynamics models, and for estimating carbon storage and cycling. However, identifying agents of tree mortality is difficult and imprecise. Although lightning kills thousands of trees each year and is an important agent of mortality in some forests, the frequency and distribution of lightning-caused tree ...
