Low‐Frequency Waves in Space Plasmas

A. Keiling, D.-H. Lee, K.-H. Glassmeier, and V. M. Nakariakov, Guest Editors



Low-frequency waves in space plasmas have been studied for many decades. Recently, there has been an abundance of new wave observations from many spacecraft missions. On the ground, magnetometer arrays and radar networks have expanded to detect low-frequency signals on a global scale with high timing accuracy. In addition, there have been tremendous advances in the capabilities of simulations to allow modeling of many of the relevant processes. This Special Issue brings together a collection of papers on recent advances of wave research in various space plasmas of our Solar System, addressing various aspects of wave physics.

Turbulence and dissipation of plasma waves have been widely investigated both observationally and theoretically. Wave dissipation is also intimately related to plasma heating. In plasma physics, however, the physical nature of these concepts still remains largely uncertain. For example, so far there has no unambiguous definition about what is the turbulence of plasma waves. Alfven waves (AWs), from large-scale MHD AWs to small-scale kinetic AWs (KAWs), are the most popular fluctuations in space plasmas. Owing to the in situ spacecraft measurements, space plasmas provide us a natural laboratory to study in-depth the turbulence and dissipation of AWs and the related plasma heating.

Papers in this special issue focus on both observational analysis and theoretical modeling related to the transition regime between large MHD scales and small kinetic scales in the continuous wave vector-spectrum of AWs. We believe that, in this transition regime, turbulence, dissipation, and heating share some common physical processes.

Although this special section is intended for the papers presented at the ST-13 session of the 12th AOGS Annual Meeting, other papers not presented in this session are equally welcome.

All manuscripts should be submitted through the GEMS Web site. For additional information please contact: jgr-spacephysics@agu.org.
