Solar Activity

1992
The magnetic cycle lasts 22 years, reversing polarity in each 11-year half. Spots reach the surface in emerging flux regions (EFR) and grow in complexity. Ephemeral regions bring considerable flux to the surface, but play no great role. Diffusion models of the cycle are discussed, but the low observed diffusion constant makes them a poor fit to reality.

Solar activity and solar neutrino flux

Nature, 1981
Among discussions of the implications of the Davis experiment1 to detect solar neutrinos, there have been several suggestions that manifestations of solar activity are related to the flux of the neutrinos2–4. For example, it has been implied that (1) the physical processes in the deep interior of the Sun are related to, or even produce, the solar ...

Solar Activity, Solar Cycle, Coordinates

1996
The structure and the dynamics of the upper atmosphere depend on the energy input from the Sun via extreme ultraviolet and X-ray radiation (XUV) and on the properties of the solar wind. Contrary to the good temporal stability of the Sun’s radiation intensity at longer wavelengths (from infrared to near ultraviolet) the energy output of the Sun is ...

Solar neutrino rate and solar activity

Geophysical & Astrophysical Fluid Dynamics, 1991
Abstract A study is made of the correlation of the rates from the solar neutrino experiment of Davis et al. (1989) with sunspot numbers for various periods of time and as a function of solar latitude. There is a measure of confirmation for the idea of a modulation of the detected rate by the magnetic field in the solar convection zone.

Solar activity and the solar wind

Reviews of Geophysics, 1979
The availability of in situ solar wind observations from the complete sunspot cycle 20 (1964–1976) suggests an examination of the changes in the character of the solar wind related to the solar cycle and comparison of these observed changes with those expected from earlier studies of solar‐terrestrial physics.

Solar activity and the solar cycle

Advances in Space Research, 2003
Abstract Solar activity prediction methods have been wide-ranging, mostly numerical, and essentially curve fitting. Thus for many years the search for physically based methods has remained elusive. Surprisingly, a new class of methods does seem to be making progress, and it relates to the structure of the field within the Sun and heliosphere.
