On Earth, high pressures and low pressures occur interchangeably. So that where two pressure systems intersect, they move the air in the same direction. But as Juno revealed the first observations of Jupiter's north pole, that doesn't seem to be the case over there. There are eight gigantic storms surrounding a ninth one, and they all move counter clockwise. With two smaller ones in between on one side that do move clockwise.

How can this be explained? How is this possible?

    $\begingroup$ Of course its possible: The countervortices have probably simply been advected away. Or a different instability is responsible for this than on Earth. There is no detailed and successful modeling of this yet though, so I don't think anybody can explain it well yet. $\endgroup$ – AtmosphericPrisonEscape Sep 23 at 12:51
  • $\begingroup$ @AtmosphericPrisonEscape Of course it is what it is, but how? The term "advection" seems to refer to HORIZONTAL movements, such as the horizontal dispersion of heat. But doesn't the collision of gas in co-rotating cyklons instead cause friction and heat? I would've guessed that perhaps enormous VERTICAL flows from a deep unknown interior would be required to dominate this anti-meteorological surface phenomena. $\endgroup$ – LocalFluff Sep 23 at 18:04

    $\begingroup$ I just said, nobody has a good model yet. So we don't know how. One can speculate much and say it should have been A or it should have been B, but unless those scenarios are tested in a 3D global circulation model, nobody will know for sure. Advection is the transport of some quantity along with the flow. Can be in any direction. But atmospheres are stratified, so horizontal advection usually dominates the vertical one. Compression and stresses cause heat, yes. Collision of gas particles is encoded in the temperature. $\endgroup$ – AtmosphericPrisonEscape Sep 24 at 10:44
  • $\begingroup$ Vertical flows: Maybe those play a role, but again, stratification would play against that, and we don't understand how Jupiters poles would have unstable stratification. Also how would material coming (maybe convecting?) from the deep suddenly gain angular momentum and form vortices? To your last point: It's certainly not "anti-meteorological". Meteorology is physics, and eveything is physics. This is just poorly understood meteorology, not magic. $\endgroup$ – AtmosphericPrisonEscape Sep 24 at 10:47
