Abstract

Abstract

The distributions of. temperature T, density N and velocity V are given using the equations coupling the MHD waves with the coronal atmosphere. It is found that coronal-hole cycle variations of some basic heliospheric parameters, such as V, T and N can be explained by the decrease of the nonradial factor a of the magnetic field in the coronal hole as solar activity is decreased.
