“…However, to cause transport, it would need to reach a non-linear stage, which is unlikely at the dayside magnetopause 7,8 . In the vortices that form in the non-linear stage of the instability, low density plasma move tailward faster than the magnetosheath plasma 48 .…”

“…Magnetic reconnection is often invoked to explain solar wind plasma entry into the magnetosphere [3][4][5][6][7] , but there are other processes as well. It has been shown that the Kelvin-Helmholtz instability can be responsible for plasma traversing the magnetopause at the terminator and further downstream in the tail 8 , where the Kelvin-Helmholtz instability reaches its non-linear stage and secondary instabilities provide transport of plasma.…”

Data from the Cluster spacecraft during their magnetopause crossing on 25 January 2002 are presented. The magnetopause was in a state of slow non-oscillatory motion during the observational period. Coherent structures of magnetosheath plasma, here typified as plasmoids, were seen on closed magnetic field lines on the inside of the magnetopause. Using simultaneous measurements on two spacecraft the inward motion of the plasmoids is followed from one spacecraft to the next, and it is found to be in agreement with the measured ion velocity. The plasma characteristics and the direction of motion of the plasmoids show that they have penetrated the magnetopause, and the observations are consistent with the concept of impulsive penetration, as it is known from theory, simulations, and laboratory experiments. The mean flux across the magnetopause observed was 0.2-0.5% of the solar wind flux at the time, and the peak values of the flux inside the plasmoids reached approximately 20% of the solar wind flux.

“…These waves may be important for diffusion across the magnetopause, and for the onset of reconnection (see e.g. Sibeck 1999). Figure 9 shows the data from the four Cluster satellites near the duskward magnetopause.…”

“…In these regions, the proton gyrofrequency and the lower hybrid frequency are about 0.3 and 10 Hz, respectively. Currents at the magnetopause, density gradients, and shear in the quasi-static electric field (Sibeck et al, 1999, and references therein) can cause waves in this frequency range. An important question is how much of the broadband emissions in the satellite frame is due to true time variations, and how much is caused by a Doppler shift due to the moving magnetopause.…”

Abstract. Highlights are presented from studies of the electric field data from various regions along the CLUS-TER orbit. They all point towards a very high coherence for phenomena recorded on four spacecraft that are separated by a few hundred kilometers for structures over the whole range of apparent frequencies from 1 mHz to 9 kHz. This presents completely new opportunities to study spatialtemporal plasma phenomena from the magnetosphere out to the solar wind. A new probe environment was constructed for the CLUSTER electric field experiment that now produces data of unprecedented quality. Determination of plasma flow in the solar wind is an example of the capability of the instrument.

“…Here we briefly outline some of the essential results and features of magnetopause structure and dynamics. The magnetopause itself has been the subject of numerous more-detailed reviews and monographs (e.g., Lundin 1988;Song et al 1995;Paschmann 1997;Sibeck et al 1999b;Farrugia et al 2001;De Keyser et al 2005;Phan et al 2005a;Lavraud et al 2011;Hasegawa 2012), and the interested reader is invited to consult these articles and reviews for more information.…”

What Controls the Structure and Dynamics of Earth’s Magnetosphere?

Unlike most cosmic plasma structures, planetary magnetospheres can be extensively studied in situ. In particular, studies of the Earth's magnetosphere over the past few decades have resulted in a relatively good experimental understanding of both its basic structural properties and its response to changes in the impinging solar wind. In this article we provide a broad overview, designed for researchers unfamiliar with magnetospheric physics, of the main processes and parameters that control the structure and dynamics of planetary magnetospheres, especially the Earth's. In particular, we concentrate on the structure and dynamics of three important regions: the bow shock, the magnetopause and the magnetotail. In the final part of this review we describe the current status of global magnetospheric modelling, which is crucial to placing in situ observations in the proper context and providing a better understanding of magnetospheric structure and dynamics under all possible input conditions. Although the parameter regime experienced in the solar system is limited, the plasma physics that is learned by studying planetary magnetospheres can, in principle, be translated to more general studies of cosmic plasma structures. Conversely, studies of cosmic plasma under a wide range of conditions should be used to understand Earth's
