One important issue is how the energy gets redistributed from the warmest
layers near the surface throughout the troposphere by radiative - convective processes, e.g.what is the shape of the environmental lapse rate curve.
Also the sharp increase is more evident in the whole layer 0 - 1800 m than in the shallow
layers near the surface, but note that 50 % coverage was achieved for the layer 900-1800 m only since 2005.
This layering results from a strong density gradient: water
layers near the surface are less salty and therefore less dense, while bottom waters are the densest.

surface water may weaken the cold tongue if the Ekman pumping doesn't reach down below the thermocline to bring up colder water, and weakened trade winds would have a similar effect through reduced Ekman pumping
near the equator.

This is to be expected because the spin - up of the wind - driven ocean circulation speeds up the currents (Ekman transport) which carry heat out of the tropics in the
near -
surface layers toward the subtropical ocean gyres.
The oceans are not a single reservoir for CO2, but a combination of
near surface waters and deeper

For the
surface layers near the ground, warming occurs because the flux from the ground remains fixed.
Right —
near the ground, in the

Ocean measurements track the temperatures in the

is dissipated by damping of gravity waves in the bulk of the air (from thunderstorm CAPE energy) and 1/2 of the remainder is dissipated in the boundary
layer (the part dissipated
near the
surface is the accessible part by conventional means)... well, you get the idea.
The areas where water samples drawn from
near -
surface layers had traces of the natural contaminants from the deep shale
layers showed no relationship to past or current gas drilling activity, the researchers reported.
Furthermore, a deeper upper
layer of warm
surface water may weaken the cold tongue if the Ekman pumping doesn't reach down below the thermocline to bring up colder water, and weakened trade winds would have a similar effect through reduced Ekman pumping
near the equator.
Changes in convection and cloud formations through altered air moisture (CAPE) could have implications for the coupled mode mechanisms, as would a deeper thermocline (usually situated
near the bottom of the warm
surface layer).
The effect where, adding a «new» absorption band and increasing the absorption, there may initially be warming of the colder
layers, etc, followed by a stage of upper level or
near - TOA cooling — this includes the warming from absorption from increased radiation from the
surface + troposphere — which will be greater when more of the spectrum, especially
near wavelengths where the emitted spectral flux change is greatest, has a greater amount of absorption.
The ability of a band to shape the temperature profile of the whole atmosphere should tend to be maximum at intermediate optical thicknesses (for a given band width), because at small optical thicknesses, the amounts of emission and absorption within any
layer will be small relative to what happens in other bands, while at large optical thicknesses, the net fluxes will tend to go to zero (except
near TOA and, absent convection, the
surface) and will be insensitive to changes in the temperature profile (except
near TOA), thus allowing other bands greater control over the temperature profile (depending on wavelength — greater influence for bands with larger bandwidths at wavelengths closer to the peak wavelength — which will depend on temperature and thus vary with height.
For the Ekman pumping (one good example of the Ekman pumping is the so - called «cold tongue»
near in the eastern part of the Pacific
near the Equator), the stability is not so important, but rather the depth of the upper warm
surface layer.
Even so the proportion and volumes involved, of the total volumes, look far to small to get rid of the
surface layers excess energy, nowhere
near enough interchange.
That lower boundary
layer of the atmosphere is the
surface and since the atmosphere and the
surface are in
near steady state equilibrium is the best indication that much of the heat transfer takes place at that boundary.
You know, for a little while there I even thought that Bob T himself (who is undoubtedly an interesting fellow) might even be sharp enough to appreciate that the coupling of increased atmospheric CO2 and increased seawater N nutrient levels to produce enhanced cyanobacterial productivity in
near surface layers of the oceans would also produce the weather - moderating effects listed above (particularly in the areas where tropical storms are «brewed»).
α is essentially a function of the

The waters that underlie the

A National Research Council panel was convened to examine observed trends of temperature

The pattern of temperature change through the
layers of the atmosphere, with warming
near the

In 2010, the Yale Project on Climate Change released a study claiming that «less than half of Americans (45 percent) understand that carbon dioxide traps heat

Without radiative cooling at altitude, tropospheric temperatures above the
near surface layer would rise to
near surface Tmax.
We present an analysis to illustrate why temperature values at specific levels will depend on wind speed, and with the same boundary
