Slow and fast solar wind acceleration near solar maximum
Advances in Space Research, 2002Abstract 2-site measurements of interplanetary scintillation (IPS) provide measurements of solar wind speed in regions of the heliosphere which are otherwise inaccessible. We present results from co-ordinated observations made with the EISCAT and MERLIN facilities during 1999 and 2000, covering heliocentric distances from 7 to 80 solar radii (R ...

The coronal source of the slow solar wind
Solar Physics, 1989Periods of very low solar wind velocity at 1 AU, during the interval from 1977 to 1983, are identified and mapped back to the coronal source surface at 2.5 R⊙. In total 25 such low-velocity events were found. Inferred source locations were characterized with respect to their position relative to the coronal neutral line. The study showed that in 17 out

Stationarity of Fast and Slow Solar Wind
2006Theories of turbulence rely on the ability to view physical fields as stationary random variables and to relate ensemble and time averages through the ergodicity assumption. This property is however poorly realized in the solar wind where the power injection mechanisms have large fluctuations over long periods due to solar rotation and to the solar ...

Semiempirical Models of the Slow and Fast Solar Wind
Space Science Reviews, 2011Coronal holes can produce several types of solar wind with a variety of compositional properties, depending on the location and strength of the heating along their open magnetic field lines. High-speed wind is associated with (relatively) slowly diverging flux tubes rooted in the interiors of large holes with weak, uniform footpoint fields; heating is ...

Sleepy sun spreads slow solar wind
New Scientist, 2014A recent slowdown in solar activity gives the first clue to a period of dramatic solar behaviour 350 years ago – and a glimpse of what the sun may do ...
