North-south asymmetry of the polar solar wind and some characteristics of solar magnetic field

We have found correlated variations of the yearly averaged north-south asymmetry in the polar solar wind speed ( Delta sub(s) sub(o) sub(l) ) and the ratio of the zonal quadrupolar to the zonal dipolar contribution in the inferred coronal magnetic field during the declining phase of sunspot cycle 21. A physically meaningful association between Delta sub(s) sub(o) sub(l) and some polar solar magnetic field proxies is also observed during the low sunspot activity periods of the above cycle.
