متن کاملAre coronal holes the only source of fast solar wind at solar minimum?
[1] A two-dimensional (2-D) MHD model of an Alfvén-wave-driven solar wind in the heliospheric meridional plane is presented whereby the consequences of a magnetic field distribution at the Sun that digresses from the standard dipole structure, often used in 2-D MHD models, are explored. The latitudinal distribution of open magnetic flux is specified at the solar surface, with a clear distinctio...
متن کاملAngular Distribution of Solar Wind Magnetic Field Vector at 1 Au
We study the angular distribution of the solar wind magnetic field vector at 1 AU and its solar cycle dependence using ACEobservations. A total of twelve27.27 day(the duration of a solar rotation) intervals during the solar maximum, the solar minimum, as well as the ascending and descending phases of solar cycle 23 are examined. For all selected intervals, we obtain the angular distribution ...
متن کاملThe Turbulent Magnetohydrodynamic Cascade: Applications of Third-Moment Theory to the Solar Wind at 1 AU
Velocity and magnetic field fluctuations in the solar wind show evidence that non-linear turbulent dynamics are present in the interplanetary medium. The cascade of energy created by these turbulent processes may provide a mechanism for in situ heating of the solar wind plasma. We perform three studies analyzing the turbulent energy cascade at 1AU using 10 years of data from the Advanced Compos...
متن کاملSolar wind turbulence and shear: A superposed‐epoch analysis of corotating interaction regions at 1 AU
[1] A superposed‐epoch analysis of ACE and OMNI2 measurements is performed on 27 corotating interaction regions (CIRs) in 2003–2008, with the zero epoch taken to be the stream interface as determined by the maximum of the plasma vorticity. When the measurements are rotated into the local‐Parker‐spiral coordinate system, the shear is seen to be abrupt. Converging flows are seen; about half of th...
