Mixing of shear Alfven wave packets
The general problem of the enhanced dissipation of shear-Alfven waves and, in particular, their ”phase mixing”, resulting from their propagation in inhomogeneous background magnetic fields, is considered from a different view point It is shown that the dissipative mechanism proceeds essentially as the accelerated diffusion of a passively advected tracer, i.e. its ”mixing” by inhomogeneous flows...
متن کاملPropagation of Alfvén Waves at the Plasma Sheet Boundary Layer
Recently, observations from the Polar and Cluster satellites have indicated that largeamplitude kinetic Alfvén waves are observed throughout the plasma sheet, particularly at the plasma sheet boundary layers, during substorms. These waves may be directly produced by reconnection processes in the tail, or indirectly through linear or nonlinear mode conversion or by localized plasma flows in the ...
متن کاملKinetic dendrite in the boundary-layer model
Within trie boundary-layer model and by taking into account only interface kinetics (isotropic or anisotropic), we find a contmuous set of « kinetic » dendrites. This solution exists at arbitrary supercooling A in the 2Dand 3D-axisymmetric cases and reduces to the usual dendrites with parabolic tails at A ~ l, and « angular » dendrites at A ~ l. In contrast with classical Ivantsov dendrites, th...
متن کاملParticle in Cell-Monte Carlo Collisions of a Plasma Column Driven by Surface Wave Plasma Discharges
In this work, applicability of Particle in Cell-Monte Carlo Collisions (PIC-MCC) simulation method for better understanding of the plasma physical mechanisms and real important aspects of a plasma column driven by surface wave plasma discharges that is used in plasma antennas is examined. Via the implementation of geometry and physical parameters of the plasma column to an Object Oriented PIC-M...
متن کاملSome properties of Alfvén waves: Observations in the tail lobes and the plasma sheet boundary layer
[1] We report properties of substorm-related, globally excited Alfvén waves on a temporal scale of 6 to 300 s (3.3 to 167 mHz) at geocentric distances between 5 and 6 RE. The waves were observed in the tail lobes and the plasma sheet boundary layer (PSBL) by the Polar satellite. In each region we made the following observations: (1) The tail lobe Alfvén waves started at substorm onset as determ...
