Self-organized criticality in the substorm phenomenon and its relation to localized reconnection in the magnetospheric plasma sheet
(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, ...
Ion acoustic damping effects on parametric decays of Alfvén waves: Right-hand polarization
(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 ...
Incoherent scatter radar estimation of F region ionospheric composition during frictional heating events
(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 ...
Phase transition-like behavior of the magnetosphere during substorms
(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 ...
Parametric decays, stabilization effects, and electrostatic instabilities due to finite-amplitude Alfvén waves in a fast solar wind-like plasma
(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 ...
Particle-in-cell simulation of incoherent scatter radar spectral distortions related to beam-plasma interactions in the auroral ionosphere
(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 ...
Postdispersal seed predation on sisyrinchium arenarium (Iridaceae) at two elevations in the central Chilean Andes
(Institute of Arctic and Alpine Research, 2002)
Postdispersal seed predation in alpine communities has received surprisingly little attention. We evaluate the magnitude of seed predation by ants and avian granivores in the perennial herb Sisyrinchium arenarium through ...
Geodynamic conditions resulting from the 2010 earthquake and tsunami in the coast of central Chile. The case of Pichilemu Condiciones geodinámicas derivadas del terremoto y tsunami de 2010 en la costa de Chile central. El caso de Pichilemu
(Revista de Geografia Norte GrandeAvda.Vicuna Mackenna 4860Macul-Santiago, 2015)
© 2015, Revista de Geografia Norte Grande, All rights reserved.The earthquake and tsunami of 2010, triggered changes in the geomorphological and sedimentary dynamics along the coast of Pichilemu, in central Chile. These ...
Observed and predicted climate variability and climate change in the Altiplano of northern Chile Variabilidad y cambios climáticos observados y esperados en el altiplano del norte de Chile
(Revista de Geografia Norte GrandeAvda.Vicuna Mackenna 4860Macul-Santiago, 2015)
© 2015, Revista de Geografia Norte Grande. All rights reserved.This study analyses temperature, rainfall irregularity and droughts in the Altiplano of Northern Chile at different temporal and spatial scales using data from ...
