The reason that the temperature drops with altitude is that most energy is
transferred near the surface.

So, for example, a big part of what drives a hurricane is the fact that you've got a lot of warm water
near the
surface of the ocean that is
transferring heat into the air, and that's what's moving up, and that is a big part of then what's propelling the entire bigger storm system.
For decades in neuroscience, the most widely accepted model posited that short - term memories form rapidly in the hippocampus and are later
transferred to the prefrontal cortex
near the brain's
surface for long - term storage.
That's faster than the 56 MBps category average, but nowhere
near the Samsung ATIV's
transfer rate (170 MBps) or the
Surface Pro (124 MBps).
I believe what Jerry is refering to is the idea of using a column of spinning air to
transfer the mechanical energy from CAPE (potential buoyant energy of hot and / or humid air
near the
surface) in an updraft to the
surface.
I can not recall them anymore; however, if I remember correctly there were a number of studies that discussed the apparent wave characteristics of approaching fronts in the early 1990's regarding the compression of the stratospheric region and the effect it had on the
transfer of tropospheric temperatures into space
near terrestrial
surface features.
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.
Four mechanisms are involved in that, IR radiation, latent heat
transfer through evaporation, conduction (significant only over very short distances
near the
surface) and convection (not across the
surface).
The net result is an upward
transfer of infrared radiation from warmer levels
near the Earth's
surface to colder levels at higher altitudes.
As evident in the figures the
near surface air temperatures are actually warmer over the Arctic Ocean (by over 1 °C in large areas) when the sea ice absorbs solar radiation and
transfers some of this energy as sensible heat back into the atmosphere.
Thus, I think the DALR is a steady state condition that arises because, in the
near surface atmosphere, convection is the dominate heat
transfer mode and it is a compressible fluid with a gravity imposed pressure gradient, hence convection is constrained by the DALR.

When the sun goes down, the
transfer is from
near the
surface to the
surface, not from the cooler deep ocean.
The shape of the CO2 band is such that, once saturated
near the center over sufficiently small distances, increases in CO2 don't have much affect on the net radiative energy
transfer from one layer of air to the other so long as CO2 is the only absorbing and emitting agent — but increases in CO2 will reduce the LW cooling of the
surface to space, the net LW cooling from the
surface to the air, the net LW cooling of the atmosphere to space (except in the stratosphere), and in general, it will tend to reduce the net LW cooling from a warmer to cooler layer when at least one of those layers contains some other absorbing / emitting substance (
surface, water vapor, clouds) or is space)
What both Willis and Pekka miss is that climatic temperature gradients high aloft (http://www.ncdc.noaa.gov/file/1328) bear little resemblance those found
near the
surface, where pole - ward heat
transfer largely takes place.
