The point isn't a «perpetual increase in atmospheric pressure» — that's a misnomer — if you consider the MASS of the atmosphere that is continuously «pumped» from cold air to hot air to cold air again, high up in the atmosphere — that creates «potential energy» from the kinetic energy of the convection — adiabatic expansion of the atmosphere is the result — the adiabatic compression occurs on the return trip of the previously warmed (from radiative energy) air as it completes the «cycle» as it comes back down!

Incidentally, the experiments of Tyndall and Fourier were done in closed containers to block convection and therefore do not represent open atmospheric conditions whatsoever.

Just as an El Niño produces a hotter Equator in the Pacific Ocean and generates more atmospheric convection, so there might be a subnormal mode that decreases heat, convection, and evaporation.

By Amber Bentley (Aged 11) In just 16 pages, this wonderful book covers the structure of the atmosphere, solar radiation, the water cycle, clouds, fronts, convection, air pressure, air masses, the global atmospheric circulation, making weather observations, forecasting, synoptic charts, hurricanes, regional climate, palaeoclimates and anthropogenic climate change.

14), addresses the mechanisms of atmospheric heat transfer not only via radiation but also by convection, which is not mentioned once in the IPCC's scientific reports (Ref.

«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»

My understanding is that the wet and dry lapse rates are maximum limits for atmospheric cooling with altitude beyond which convection will set in.

So, the non-radiative atmospheric thermal effect becomes an exercise in identifying at what point in the atmosphere does convection cease to dominate, which is also the point where the isentropic assumption breaks down.

I'll mention just one (of many) negative feedbacks in the atmospheric thermodynamic system — convection.

The real GHE is the reduction of surface emissivity, also possibly coupled convection as atmospheric GHG thermal - emission Poynting Vectors annihilate the UP PVs in that wavelength interval.

But in a given model you can often find ways of altering the model's climate sensitivity through the sub-grid convection and cloud schemes that affect cloud feedback, but you have to tread carefully because the cloud simulation exerts a powerful control on the atmospheric circulation, top - of - atmosphere (TOA) and surface radiative flux patterns, the tropical precipitation distribution, etc..

Thirty years later, the relevance of this study has been realized in the development of stochastic approaches to represent cumulus convection and its upscale energy transports, and in the emerging efforts to resolve these multi-scale processes in atmospheric simulations at the cloud system - resolving scale (approx. 1 km).

In the future, Romps plans to look at the distribution of lightning - strike increases around the U.S. and also explore what lightning data can tell climatologists about atmospheric convection.

All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.

The atmospheric vortex engine exploits the natural energy content of the vortex produced during upward heat convection in the atmosphere.

However, the availability of non-radiative means for vertical transport of energy, including small - scale convection and large - scale atmospheric motions, must be accounted for, as is done in our atmospheric general circulation model.

An atmospheric vortex engine (AVE) uses a controlled vortex to capture mechanical energy produced when heat is carried upward by convection in the atmosphere.

The physics that must be included to investigate the moist greenhouse is principally: (i) accurate radiation incorporating the spectral variation of gaseous absorption in both the solar radiation and thermal emission spectral regions, (ii) atmospheric dynamics and convection with no specifications favouring artificial atmospheric boundaries, such as between a troposphere and stratosphere, (iii) realistic water vapour physics, including its effect on atmospheric mass and surface pressure, and (iv) cloud properties that respond realistically to climate change.

This is incorrect because about half of the additional delta eK is a result of atmospheric convection that causes friction within the system and in contact with the earth's surfaces.

The IPCC summary is deeply flawed as a scientific document and as I have explained in other recent articles it appears impossible for increased levels of atmospheric CO2 at the puny levels caused by mankind to affect the characteristics of the atmosphere enough to significantly enhance the greenhouse effect and even if it could do so then any such effect would be quickly neutralised by the primary solar / oceanic driver and the oceans acting in conjunction with evaporation, condensation and atmospheric convection (which includes clouds and rain).

To my way of thinking «atmospheric heat can only be trapped, or slowed down, by a reduction in convection.

Answer obvious, and pertains only to anvils in frigid baths (or similar concepts), but it is completely irrelevant to the discussion at hand: it has NO relationship to atmospheric physics, due to «other factors,» such as convection and evaporation / condensation of water.

It reflects reductions in lapse rates, which in the tropics reflect reductions in the moist - adiabatic lapse rate to which moist convection tends to restore atmospheric temperature profiles.

Convection is characterized by a circulation pattern of rising and sinking air masses, and the atmospheric vertical volume transport takes place through cells of updraft and subsidence; however, these may not be coherent or stable in time and space.

Since we can not measure any individual forcing directly in the atmosphere, the models draw upon results of laboratory experiments in passing sunlight through chambers in which atmospheric constituents are artificially varied; such experiments are, however, of limited value when translated into the real atmosphere, where radiative transfers and non-radiative transports (convection and evaporation up, advection along, subsidence and precipitation down), as well as altitudinal and latitudinal asymmetries, greatly complicate the picture.

Specifically, the convection of fluid air is the dominant player in Earth's atmospheric heat dynamics.
