I presume the answer lies in admitting more of the complexity of real case into the computations: if not the spinning, irregularly surfaced sphere, then at least the huge differential in solar heating «twixt the equatorial and the polar regions, the great daily poleward energy transfers which compensate thanks in large part to massive convective systems.
What purely physical principle did Walker and Schneider appeal to in estimating the poleward energy flux of the Hadley circulation at 4.8 PW in Figure 5 of http://www.clidyn.ethz.ch/papers/annrev06.pdf (the paper Anastassia referenced above)?
For example, equatorward - moving weather systems — known as «transient eddies» — fulfill much of the poleward energy export required to balance the net energy input, with the energy transport associated with vertical motion times gross moist stability less important than in the ITCZ.
An important one is additional poleward energy transport, but contributions from local high - latitude water vapour, cloud and temperature feedbacks have also been found.
«Changes in the Poleward Energy Flux by the Atmosphere and Ocean as a Possible Cause for Ice Ages.»
Both contribute to poleward energy transport and therefore Western Europe's relatively warm climate, but they are very different and conflating them contributes to public misunderstanding of the climate system.
The polewards energy transport of the ocean is smaller in the Southern Hemisphere than in the Northern Hemisphere; this arises because of the effects of a circumpolar channel on the deep overturning circulation.

Their abstract says «energy budget calculations show that poleward atmospheric energy transport increases more in solar forcing compared to equivalent CO2 forcing simulations, which is in line with the identified strong increase in large - scale precipitation in solar forcing scenarios.»
The flow of energy between different circulation patterns is dependent on fram of reference (Eulerian vs transformed Eulerian); The Ferrel Cell is the result of some average upward motion poleward of some average downward motion with return flows at lower and higher altitudes, superimposed on the average temperature distribution.
Is less poleward transport of heat by the Gulf Stream as the AMOC weakens a positive feedback for global warming, since that energy will escape more slowly in the humid (higher water vapor GHG effect) tropics than near the poles?
Indeed that poleward shift was supposed to be accompanied by a tropospheric hot spot as the enhanced upward energy flux was then constrained by extra GHGs so that the «surplus» energy was retained in the troposphere and thereby denied to the stratosphere which then cooled as per observations and despite the «normal» warming of the stratosphere that would otherwise have been expected from the highly active sun at the time.
What drives ocean sensitivity is the sun and poleward transport of energy.
The tropical pipe becomes significantly more leaky, and greater transport into the lowermost stratosphere in the subtropics appears to be occurring, possibly in conjunction with a poleward shift in wave energy convergences.
In general, the tropical oceans will tend to show a net gain of heat, and the polar oceans a net loss, the result of a net transfer of energy polewards in the oceans.
The vertical transfer of energy is directly proportional to the poleward transport or advection of heat.
Thus when more energy enters the oceans the strength of El Nino will be enhanced relative to La Nina and the effect will be cumulative over time for so long as the sun is sufficiently active with the jets sufficiently poleward.
The Arctic surface air temperature is strongly effected by atmospheric forcing and atmospheric energy circulated poleward which creates the Arctic Winter Warming and Sudden Stratospheric warming events.
23) A returning warm pulse will try to expand the tropical air masses as more energy is released and will try to push the air circulation systems poleward against whatever resistance is being supplied at the time by the then level of solar surface activity.
For that energy to be transferred poleward instead of lost to space, it would have to encounter a resistance equal to 165Wm - 2 which would produce a «DWLR» of 2 * 165 or 330Wm - 2 + / - a touch.
Poleward and / or more zonal jetstreams mean that the troposphere is bit warmer as the rate of energy flow through the troposphere increases.
If the surface pressure distribution begins to shift to a more meridional / equatorward pattern as it did around 2000 then if previously it was in a poleward / zonal mode it is clear that warming will have ceased and cooling has begun due to more global cloudiness and less solar energy getting into the oceans.
An active sun gives more zonal jets and / or more poleward climate zones with less global cloudiness and more energy into the oceans for gradually strengthening El Ninos as compared to La Ninas and a gradual rise in global tropospheric temperatures.
Conversions of that kind must play some role in the 9.4 W / m2 of total energy carried polewards by the Hadley circulations, though I'm not clear as to what.
This circulation and its poleward heat transport must exist to balance the surface energy budget, especially the strong longwave cooling term (e.g. Warren 1996).
These zones can move poleward or equatorward, in response to changes in the Earth's energy budget.
In the tropics oceans absorb energy on average before it is transported poleward by currents and generally given up to the atmosphere.
When a large surge of polar air moves equatorward it draws a pulse of energy from the oceans in the lower latitudes and pumps it into the stratosphere where most of that energy is pushed out to space but a portion is not pushed out and descends again thus strengthening the high pressure systems on the poleward side of the mid latitude jets.
That makes sense because a cooler stratosphere weakens the inversion at the tropopause so as to provide reduced resistance to upward energy transport which would allow the jets to move poleward.
A returning warm pulse will try to expand the tropical air masses as more energy is released and will try to push the air circulation systems poleward against whatever resistance is being supplied at the time by the then level of solar surface turbulence.
The warmth from the oceans pumps energy upwards but the quiet sun prevents the poleward movement of the jets.
Due to climate change the Hadley Cell intensifies: More air moves up in the tropics (so more energy and rain in the Intertropical Convergance Zon (ITCZ — monsoon) and more air moves down in the subtropics, that also expand in poleward direction.
It will reduce the amount of energy reaching the surface compared to what it would have let in if situated more poleward.
However, Earth's surface energy balance dictates that net poleward heat transport should be symmetrical in both hemispheres.
In fact, the opposite could turn out to be true (i.e. that due to higher insolation / energy, more heat is redistributed poleward more efficiently, and HADCRUT would then demonstrate a negative bias).
Although, there is something interesting — the incovenient fact of heat flow mechanisms that do not move heat / energy poleward are, shall we say, politically incorrect?
We find that an increase in poleward heat transport by the tropical ocean results in a warming of the extra-tropics, relatively little change in the tropical temperatures, moistening of the subtropical dry zones, and partial but incomplete compensation of the planetary - scale energy transport by the atmosphere.
However the effect is to draw the jets poleward thereby reducing cloudiness and albedo so that more energy enters the oceans.
Understanding the oceans, how they gain / lose energy and how they circulate energy in 3 directions (polewards and to depth), and how the oceans, coupled with the spinning nature of the planet, power the atmosphere is the key to understanding how our climate works.
Thus the more energy from the sun the faster the hydrological cycle will run with warmer ocean surfaces, more zonal and / or more poleward jets and a faster expulsion of energy to space.
Through baroclinic instability, the potential energy associated with temperature gradients is converted into the energy in atmospheric eddies that dominate the heat and angular momentum transport poleward of the subsiding region of the Hadley cell.
