Propagation mechanism of daytime Pc 3-4 pulsations observed at synchronous orbit and multiple ground-based stations
TLDR
In this paper, the authors investigated the relationship between the Pc 3-4 pulsations at the ground stations and the compressional Pc3-4 waves in the magnetosphere.Abstract:
Observational data obtained during the last two decades show that the amplitude of daytime Pc 3-4 magnetic pulsations is controlled by the solar wind conditions. The high degree of correlation between the solar wind parameters and Pc 3-4 pulsations in the dayside magnetosphere suggests that the ultimate cause of the daytime Pc 3-4 pulsations must be the interaction of the solar wind with the earth's magnetosphere. The present paper is concerned with details regarding the control of the properties of the Pc 3-4 pulsations by the solar wind parameters, taking into account observations made at multiple ground-based stations. It is attempted to establish the relation between the daytime Pc 3-4 pulsations at the ground stations and the compressional Pc 3-4 waves in the magnetosphere. Attention is given to the most probable propagation mechanism of the daytime Pc 3-4 pulsations in the magnetosphere.read more

TL;DR: In this article, the distribution of ULF energy (frequency < 80 mHz) in the inner magnetosphere (L = 2.5-6.5) has been studied using magnetic field measurements made with the Active Magnetospheric Particle Tracers Explorers Charge Composition Explorer (AMPTE CCE) spacecraft during its whole mission of over 4 years.

Some features of field line resonances in the magnetosphere
TL;DR: In this paper, the authors examined the circumstances under which finite disturbance amplitude solutions of the coupled wave equation can be obtained in the vicinity of the resonant field line, and the relevance of recent experimental work to the problem was pointed out.

TL;DR: In this article, a theory of long-period (Pc 3 to Pc 5) magnetic pulsations is presented based on the idea of a steady state oscillation of a resonant local field line that is excited by a monochromatic surface wave at the magnetosphere.

Upstream hydromagnetic waves and their association with backstreaming ion populations: ISEE 1 and 2 observations
TL;DR: In this article, measurements from the Lepedea plasma instruments and the flux gate magnetometers on ISEE 1 and 2 are used to examine the nature of the hydromagnetic waves associated with the various classes of ions backstreaming from the earth's bow shock.

Bow shock associated waves observed in the far upstream interplanetary medium
TL;DR: In this paper, it was concluded that the waves are associated with the earth's bow shock since they only occur when projection of the interplanetary field observed at the spacecraft intersects the shock.

Anomalous transport by magnetohydrodynamic Kelvin‐Helmholtz instabilities in the solar wind‐magnetosphere interaction
TL;DR: In this paper, the anomalous tangential stress at the magnetospheric boundary caused by the instability may be of the order of 1 percent of the magnetosheath flow momentum adjacent to the boundary, and gives a contribution to the convection potential drop over the polar cap of 10-30 kV.
