Quasi-periodic Energy Release and Jets at the Base of Solar Coronal Plumes

A fat coronal plume seems to contain myriad streams arising on spine field lines, which coincidentally all have the same polarity. This might occur naturally in a "unipolar" domain, bringing to mind a line of wee birds all perching on a power line and looking into the prevailing wind. This cartoon's viewpoint would be a major contribution to understanding the switchbacks (see also the Fisk-Kasper cartoon).

The pastel colors are very nice but the authors do not explain why there are three distinct colors in the "embedded bipole" units. It's also a bit odd that one of the jetlets wanders across the plume boundary; in addition, technically, the disks representing embedded minority-polarity regions have a different geometric projection than the plume itself does.
