摘要

We have studied physical conditions of coronal magnetic field which determine solar wind velocity using interplanetary scintillation method. A flux expansion rate (f) and magnetic field energy (B) have been proposed as parameters which determine the solar wind velocity by Wang and Sheeley (1990) and by Fisk et al. (1999), respectively. However we have found that the solar wind speed has much better correlation with a ratio of those two parameters B/ f than with an individual parameter.
