The Open University ’ s repository of research publications and other research outputs Diurnal Variation in Martian Dust Devil Activity
We show that the dust devil parameterisation in use in most Mars Global Circulation Models (MGCMs) results in an unexpectedly high level of dust devil activity during morning hours. Prior expectations of the diurnal variation of Martian dust devils are based mainly upon the observed behaviour of terrestrial dust devils: i.e. that the majority occur during the afternoon. We instead find that lar...
متن کاملOxidant enhancement in martian dust devils and storms: storm electric fields and electron dissociative attachment.
Laboratory studies, numerical simulations, and desert field tests indicate that aeolian dust transport can generate atmospheric electricity via contact electrification or "triboelectricity." In convective structures such as dust devils and dust storms, grain stratification leads to macroscopic charge separations and gives rise to an overall electric dipole moment in the aeolian feature, similar...
متن کاملElectron Avalanche Statistics
Since the times of the founders of streamer theory — Raether [1], Loeb [2] and Meek [3] — a special attention has been paid to high populated electron avalanches possessing potential to overgrowing into streamers. One of the basic problem that has not been resolved so far concerns anomalous statistical behavior of big avalanches with electron populations n > 10. The mentioned anomaly consists i...
متن کاملThe Asymmetric Avalanche Process
An asymmetric stochastic process describing the avalanche dynamics on a ring is proposed. A general kinetic equation which incorporates the exclusion and avalanche processes is considered. The Bethe ansatz method is used to calculate the generating function for the total distance covered by all particles. It gives the average velocity of particles which exhibits a phase transition from an inter...
متن کاملMartian Dust Belts: Waiting for Discovery
Mukai (1992), Krymskii et al. (1992), Tátrallyay et al. (1992), Juhász et al. (1993), Kholshevnikov et al. (1993), In this paper, we present modeling results of the presumed dust belts of Mars. We combine recently obtained theoretical Ishimoto and Mukai (1994), Krivov (1994), Krivov and results in dynamics of circumplanetary dust grains with up-toTitov (1994), Sasaki (1994), Juhász and Horányi ...
