One-parameter representation of the daily averaged solar-wind velocity
Abstract
An empirical formula was found to describe the dependence V(S) of the daily average solar-wind velocity V on the coronal-hole area S on the visible side of the Sun in the form of first-and second-order Taylor expansions. The results can be used for approximate evaluation of the solar-wind velocity at the Earth's orbit from coronal-hole observations.
