Solar Wind Sources and Their Variations Over the Solar Cycle

Space Science Reviews, 2007
In this paper I will briefly summarize the present status of our knowledge on the four different sorts of solar wind, their sources and their short- and long-term variations. First: the fast solar wind in high-speed streams that emerges from coronal hole regions.

Missing solar cycle hypothesis and basic statistical regularities of solar cycles

Geomagnetism and Aeronomy, 2012
The basic statistical properties of solar cycles, including the Gnevyshev-Ol’ rule, the Waldmeier effect, and the amplitude-period effect, are tested using data on the number of sunspot groups for 1700–1996, considering the hypothesis about a missing solar cycle in the late 18th century. The results show that the division of the long cycle of 1784–1800

The solar wind throughout the solar cycle

2008
The existence of solar corpuscular radiation (SCR) was conjectured by Biermann (1951) based on the fact that the ion tails of comets always point radially away from the Sun. Earlier it had been thought that this was due to solar radiation pressure, but when the relevant cross-sections were measured it became clear that these were far too small. This is

The Solar Cycle (L)

1969
As an index for the solar ‘activity’ the sunspot relative numbers have been generally adopted: they were defined by Wolf, Wolffer and Brunner, at the Zurich Observatory where they are still now regularly determined on the basis of observational work done over the whole world.
