Shear interaction and acceleration of a corotating stream detected by Parker Solar Probe

Astronomy & Astrophysics
Recent analysis of Parker Solar Probe (PSP) and Solar Orbiter data indicates that fluctuation energy is transferred to the bulk flow in fast streams of the solar wind at heliocentric distances of between 15 and 120 R⊙.

Field-aligned currents are strongly modulated by corotating solar wind high-speed streams

Journal of Space Weather and Space Climate
Birkeland field-aligned currents (FACs) are associated with solar wind-magnetosphere energy coupling leading to substorms/convection events. FAC intensity enhancements have been studied during geomagnetic storms driven by interplanetary coronal mass ...

Introduction to special issue on high speed solar wind streams and geospace interactions (HSS-GI) [PDF]

, 2009
This special issue of the Journal of Atmospheric and Solar-Terrestrial Physics is devoted to research into high speed solar wind streams (HSSs) and their effects on the region of near-Earth space commonly known as ‘geospace’.

First imaging of corotating interaction regions using the STEREO spacecraft [PDF]

, 2008
Plasma parcels are observed propagating from the Sun out to the large coronal heights monitored by the Heliospheric Imagers (HI) instruments onboard the NASA STEREO spacecraft during September 2007. The source region of these out-flowing parcels is found

Ionospheric response to the corotating interaction region-driven geomagnetic storm of October 2002 [PDF]

, 2009
Unlike the geomagnetic storms produced by coronal mass ejections (CMEs), the storms generated by corotating interaction regions (CIRs) are not manifested by dramatic enhancements of the ring current. The CIR-driven storms are however capable of producing

Superposed epoch analysis of high-speed-stream effects at geosynchronous orbit: Hot plasma, cold plasma, and the solar wind [PDF]

, 2008
Superposed epoch analyses of magnetospheric plasma analyzer (MPA) data from Los Alamos National Laboratory (LANL) satellites are performed to reveal the density, temperature and flow velocity behavior of the hot ion plasma (0.1–45 keV), the hot electron ...

Magnetic field at geosynchronous orbit during high-speed stream-driven storms: Connections to the solar wind, the plasma sheet, and the outer electron radiation belt [PDF]

, 2010
Superposed-epoch analysis is performed on magnetic field measurements from five GOES spacecraft in geosynchronous orbit during 63 high-speed stream-driven storms in 1995–2005. The field strength and the field stretching angle are examined as functions of

A three‐dimensional model of corotating streams in the solar wind 2. Hydrodynamic streams [PDF]

Journal of Geophysical Research: Space Physics, 1980
This paper explores theoretical aspects of corotating solar wind dynamics on a global scale by means of numerical simulations executed with a nonlinear, inviscid, adiabatic, single‐fluid, three‐dimensional (3‐D) hydrodynamic formulation. The study begins with a simple hypothetical 3‐D stream structure defined on a source surface located at 35 RS and ...

Processes associated with particle transport in corotating interaction regions and near stream interfaces [PDF]

Journal of Geophysical Research: Space Physics, 2001
Pioneer and Ulysses observations of energetic particles and solar wind plasma and magnetic fields are analyzed to study particle transport in corotating interaction regions (CIRs) and near stream interfaces (SIs). Energetic particle diffusion with a lowered coefficient near the SIs as compared with the free solar wind may account for the energetic ...
