The researchers» interpretation is that the jet is «serpentine and inhomogeneous»
because it emits radiation over a range of frequencies and from different zones, which
change their orientation due to the instabilities in the jet, or to
orbital motions.
The Arctic took another 3,000 - 4,000 years to warm this much, primarily
because of the fact that the Northern Hemisphere had huge ice sheets to buffer warming, and the fact that
changes in ocean currents and Earth's
orbital configuration accelerated warming in the south.
Such
changes are much less pronounced than the seasonal
changes on Earth
because Jupiter's equator is inclined at only 3.2 ° to its
orbital plane whereas Earth's is at 23.5 °.
So here's an attempt: When temperatures
change because of an
orbital forcing, you've got a strong CO2 feedback
because the CO2 in the atmosphere was in equilibrium with the CO2 in the oceans before temperatures
changed.
Finding a similar trend in the Southern Hemisphere was somewhat unexpected
because the effects of the
orbital changes should be opposite there.
That's
because orbital speed
changes with position within the elliptical orbit.
