Abstract:    We have remeasured the rate of coronal inflows during 1996-2001, taking into account multiple occurrences per day, and have displayed the results in Carrington stack plots to study their long-term behavior. The stack plots show long-lived recurrence patterns related to the sectorial component of the Sun's large-scale field. In particular, most inflows are parts of streams that last for several months and occur where the sectorial field has strong gradients. The occurrence rate occasionally approaches ~1 hr-1 near sunspot maximum when the sectorial field is strong and the streamer belt is greatly distorted from its flattened equatorial configuration. The link between coronal inflows and sector magnetism suggests that the inflows are by-products of a global recycling process in which nonaxisymmetric open flux is provided by active regions and dissipated by differential rotation, supergranular diffusion, and meridional flow.
