CLASSIFICATION OF THE INTERPLANETARY SHOCKS BY SHOCK DRIVERS [PDF]
Journal of The Korean Astronomical Society, 2002 From the data of solar wind observation by ACE spacecraft orbiting the Earth-Sun Lagrangian point, we selected 48 forward interplanetary shocks(IPSs) occurred in 2000, maximum solar activity period. Examining the profiles of solar wind parameters, the IPSs are classified by their shock drivers.

In situ local shock speed and transit shock speed [PDF]
Annales Geophysicae, 1998 A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

Interaction of a strong interplanetary shock with the termination shock [PDF]
Journal of Geophysical Research: Space Physics, 1999 The 1991 global merged interaction region (GMIR) shock is a strong forward shock observed from Voyager 2 on day 146 of 1991 at 34.6 AU. As the GMIR shock propagated out‐ward in the distant heliosphere, it eventually encounters the termination shock. We study the interaction of the GMIR shock with the termination shock taking into account the influence ...

Forbush precursory increase and shock-associated particles on 20 October 1989 [PDF]
Annales Geophysicae, 2002 Strong interplanetary disturbances may affect cosmic ray protons tremendously with energies less than 1 GeV, increasing their intensity by hundreds of percents, but they are not so effective for protons of higher energies.

Unusual enhancement of ~ 30 MeV proton flux in an ICME sheath region
Earth, Planets and Space, 2021 In gradual Solar Energetic Particle (SEP) events, shock waves driven by coronal mass ejections (CMEs) play a major role in accelerating particles, and the energetic particle flux enhances substantially when the shock front passes by the observer.

Statistical study on interplanetary drivers behind intense geomagnetic storms and substorms
Earth and Planetary Physics, 2019 Geomagnetic storms and substorms play a central role in both the daily life of mankind and in academic space physics. The profiles of storms, especially their initial phase morphology and the intensity of their substorms under different interplanetary ...

Multiple spacecraft observations of interplanetary shocks: Characteristics of the upstream ULF turbulence [PDF]
, 1982 All interplanetary shocks observed by ISEE-3 and either ISEE-1 or ISEE-2 or both in 1978 and 1979 are examined for evidence of upstream waves. In order to characterize the properties of these shocks it is necessary to determine accurate shock normals. An

Sources of interplanetary shocks [PDF]
Advances in Space Research, 1995 Abstract The sources of interplanetary shocks are reviewed from the standpoint of today's knowledge. Recent progress from both new and accumulated observations and models indicates that contributions from the two major sources of the shocks: CMEs and stream interactions, have distinctive radial, latitudinal and temporal dependencies.

Plasmaspheric High‐Frequency Whistlers as a Candidate Cause of Shock Aurora at Earth
Geophysical Research Letters, 2023 Auroral brightening driven by interplanetary shocks on Earth's closed magnetic field lines is commonly attributed to the 0.1–10 keV electron precipitations by electron cyclotron harmonic waves and whistler‐mode chorus waves in the low‐density region.
