Solar cycle dependence of global distribution of solar wind speed

Abstract

A review is given of observational results concerning the solar cycle dependence of the global structure of solar wind speed distribution during the years from 1973 to 1987. Since observations of solar wind speed in 3-dimensional space can only be made by the interplanetary scintillation method which has been carried out over one sunspot activity cycle since the early 1970's, the review is based on IPS observations. The low-speed regions tend to be distributed along neutral lines which are derived on the source surface, so comparisons between speed distribution and the neutral line are discussed.
