(John Wiley and Sons Inc., 2019)Detailed temperature reconstructions over the past 2,000 years are important for contextualizing modern climate change. The midlatitude SE Pacific is a key region in this regard in terms of understanding the climatic ...
-
(Blackwell Publishing Ltd, 1998)We study the stability of electromagnetic waves for nongyrotropic velocity distribution functions in a solar-wind-like plasma. The dispersion relation is solved numerically in closed form. On the basis of recently reported ...
-
(Blackwell Publishing Ltd, 2008)Alfvén/ion-cyclotron waves have been observed in several regions of the magnetosphere. Parametric decays of finite amplitude Alfvén/ion- cyclotron waves in the presence of He+ ions and a mixed population of thermal and hot ...
-
(Blackwell Publishing Ltd, 2011)A method is developed for estimating F region ion composition from incoherent scatter radar (ISR) measurements during times of frictional ion heating. The technique addresses ion temperature-mass ambiguities in the IS ...
-
(Blackwell Publishing Ltd, 2000)It is well known that in plasmas with β = (νs/νA)2 < 1 (νs is the ion acoustic velocity and νA is the Alfvén velocity), Alfvén waves propagating along an external magnetic field can have three kinds of parametric ...
-
(Blackwell Publishing Ltd, 2001)We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
-
(Blackwell Publishing Ltd, 2005)[1] It is shown that ion-acoustic waves propagating along an external magnetic field and generated by parametric decays of circularly polarized finite amplitude waves have the properties of ion-acoustic waves observed ...
-
(Blackwell Publishing Ltd, 2009)It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
-
(Blackwell Publishing Ltd, 2007)The effects of a finite-amplitude Alfvén wave in a plasma system with a proton and an alpha-particle beam, are studied. The system is described by a fourteenth-order polynomial providing, thereby, many decay channels for ...
-
(Blackwell Publishing Ltd, 2011)An electrostatic parallel particle-in-cell (EPPIC) code that allows for particle beam injections and multiple boundary conditions is used to investigate the beam-plasma interaction and its manifestations in the incoherent ...
-
(Blackwell Publishing Ltd, 2000)The behavior of substorms as sudden transitions of the magnetosphere is studied using the Bargatze et al. [1985] data set of the solar wind induced electric field vBs and the auroral electrojet index AL. The data set is ...
-
(Blackwell Publishing Ltd, 2016)©2016. American Geophysical Union. All Rights Reserved. The Unsolved Problems of Magnetospheric Physics Workshop was held in September 2015 in Scarborough, UK. In contrast to most other meetings, people were specifically ...
-
(Blackwell Publishing Ltd, 2000)Evidence is presented that suggests that there is a significant self-organized criticality (SOC) component in the dynamics of substorms in the magnetosphere. We assume that observations of bursty bulk flows, fast flows, ...
-
(Blackwell Publishing Ltd, 2011)During the last decade, a number of studies have shown that turbulent processes in the plasma sheet are very important for the analysis of the formation of quasi-stable plasma sheet configurations. The existence of this ...
