Self-organized criticality in the substorm phenomenon and its relation to localized reconnection in the magnetospheric plasma sheet Klimas, A. J.; Valdivia Hepp, Juan; Vassiliadis, D.; Baker, D. N.; Hesse, M.; Takalo, J. (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, ...
Particle-in-cell simulation of incoherent scatter radar spectral distortions related to beam-plasma interactions in the auroral ionosphere Diaz, M. A.; Oppenheim, M.; Semeter, J. L.; Zettergren, M. (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 ...
Sitnov, M. I.; Sharma, A. S.; Papadopoulos, K.; Vassiliadis, D.; Valdivia Hepp, Juan; Klimas, A. J.; Baker, D. N. (Blackwell Publishing Ltd, 2000)The behavior of substorms as sudden transitions of the magnetosphere is studied using the Bargatze et al.  data set of the solar wind induced electric field vBs and the auroral electrojet index AL. The data set is ...
