We present a novel investigation into the relationship between simple
estimates of magnetic flux balance and the Ne VIII Doppler velocity
partitioning of a large equatorial coronal hole observed by the Solar
Ultraviolet Measurements of Emitted Radiation spectrometer (SUMER) on the Solar
and Heliospheric Observatory (SOHO) in November 1999. We demonstrate that a
considerable fraction of the large scale Doppler velocity pattern in the
coronal hole can be qualitatively described by simple measures of the local
magnetic field conditions, i.e., the relative unbalance of magnetic polarities
and the radial distance required to balance local flux concentrations with
those of opposite polarity.Comment: To appear ApJL (June
