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.

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 ...

Dynamics of He++ Ions at Interplanetary and Earth’s Bow Shocks
Universe, 2022 Experimental investigations of the fine plasma structure of interplanetary shocks are extremely difficult to conduct due to their small thickness and high speed relative to the spacecraft.

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.

The physics of space weather/solar-terrestrial physics (STP): what we know now and what the current and future challenges are [PDF]
Nonlinear Processes in Geophysics, 2020 Major geomagnetic storms are caused by unusually intense solar wind southward magnetic fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the occurrence of future interplanetary events?

Arrival times of Flare/Halo CME associated shocks at the Earth: comparison of the predictions of three numerical models with these observations [PDF]
Annales Geophysicae, 2002 The arrival times at L1 of eleven travelling shocks associated both with X-ray flaring and with halo CMEs recorded aboard SOHO/LASCO have been considered.
