Properties of Kelvin-Helmholtz waves at the magnetopause under northward interplanetary magnetic field: Statistical study
Wang, Chi; Li, Wenya; Tang, Binbin +3 more
We search the plasma and magnetic field data of the Time History of Events and Macroscale Interactions during Substorms (THEMIS) probes B and C during 2008 and 2009 for observation evidences of the Kelvin-Helmholtz instability (KHI). Fourteen KHI events with rolled-up vortices are identified under the northward interplanetary magnetic field (IMF) …
Magnetopause reconnection and energy conversion as influenced by the dipole tilt and the IMF Bx
Palmroth, Minna; Hoilijoki, Sanni; Souza, Vitor M. +2 more
We study the effect of Earth's dipole tilt angle and interplanetary magnetic field (IMF) Bx and By components on the location of reconnection and the energy conversion at the magnetopause. We simulate southward IMF satisfying both inward- and outward-type Parker spiral conditions during three different dipole tilt angles usin…
Statistical study of chorus wave distributions in the inner magnetosphere using Ae and solar wind parameters
Aryan, Homayon; Yearby, Keith; Balikhin, Michael +3 more
Energetic electrons within the Earth's radiation belts represent a serious hazard to geostationary satellites. The interactions of electrons with chorus waves play an important role in both the acceleration and loss of radiation belt electrons. The common approach is to present model wave distributions in the inner magnetosphere under different va…
On nonlinear cascades and resonances in the outer magnetosphere
Kozak, L.; Amata, E.; Kronberg, E. A. +10 more
The paper addresses nonlinear phenomena that control the interaction between plasma flow (solar wind) and magnetic barrier (magnetosphere). For the first time we demonstrate that the dominant solar wind kinetic energy: (i) excites boundary resonances and their harmonics which modulate plasma jets under the bow shock; (ii) produces discrete three-w…
MHD and kinetic analysis of flow bursts in the Earth's plasma sheet
Dandouras, I.; Reme, H.; Cao, JinBin +6 more
In an attempt to study the flow bursts in the Earth's plasma sheet we select an event that took place on August 7, 2004 in the expansion phase of a substorm, using data from the geomagnetic index, solar wind data, plasma and magnetic field observations from C1 Cluster satellite (the Cluster mission has 4 satellites) and from Double Star TC-1 satel…
