Also a useful tie in for the physics topic on «radiation».

One is to acknowledge that calculation of radiation transport through a partially opaque atmosphere is one of those problems that seems easy until you try to write down the equations, and then you find it's a monster — the great mathematical physicist S. Chandrasekhar spent years working on it and wrote a book full of equations on stellar atmospheres that I think hardly anyone in atmospheric physics even tries to read.

By the way, my arguments assume that tokamak physics and technology works well and is reasonably simple, meaning that not many more components will have to be added to the system to allow it to operate on a steady basis for very long periods of time between the long shutdowns needed to change out radiation - damaged, radioactive materials.

Most people don't understand the details of atmospheric physics or principal components analysis, and so take many statements about «back - radiation» and «hockeysticks» on trust.

Looking in a textbook about atmospheric physics, meteorology or climate physics it is getting quite clear that atmospheres are more complex then just reducing their thermal structure on the effects of solar radiation and greenhouse gases alone.

The physics of greenhouse gases (= by definition gases that absorb thermal radiation) is essential to get appropriate physical models explaining the observations quantitatively and allow to evaluate what happen on changed conditions by virtual experiments.

In terms of building physics, this increases the probability that condensation might form on the outer surface of the façade due to the cooling effect of long - wave radiation of heat during the night.

The meeting will mainly cover the following themes, but can include other topics related to understanding and modelling the atmosphere: ● Surface drag and momentum transport: orographic drag, convective momentum transport ● Processes relevant for polar prediction: stable boundary layers, mixed - phase clouds ● Shallow and deep convection: stochasticity, scale - awareness, organization, grey zone issues ● Clouds and circulation feedbacks: boundary - layer clouds, CFMIP, cirrus ● Microphysics and aerosol - cloud interactions: microphysical observations, parameterization, process studies on aerosol - cloud interactions ● Radiation: circulation coupling; interaction between radiation and clouds ● Land - atmosphere interactions: Role of land processes (snow, soil moisture, soil temperature, and vegetation) in sub-seasonal to seasonal (S2S) prediction ● Physics - dynamics coupling: numerical methods, scale - separation and grey - zone, thermodynamic consistency ● Next generation model development: the challenge of exascale, dynamical core developments, regional refinement, super-parametrization ● High Impact and Extreme Weather: role of convective scale models; ensembles; relevant challenges for model development

Correct physics tells us that the Sun's radiation can, on average, only raise the temperature in colder regions well up in the troposphere.

The big difference between this scenario is that the radiation from the lamp AND the radiation from the glass originate in materials at significantly higher temperatures than the gases and hence heat IS transferring from HOT to COLD unlike the fanciful «back radiative greenhouse effect» which truly defies the laws of Physics relying instead on pixie dust magic!

The biggest error of all the errors in the physics of the radiative greenhouse conjecture is that they «explain» the surface temperature of 288K using Stefan - Boltzmann calculations based on the direct solar radiation PLUS about TWICE as much supposed thermal energy input from the colder atmosphere.

The sensitivity of the models is, as I think you are saying, constrained by it's parametrizations, which are bounded by observational data on TOA radiation data etc. (although not all very tightly constrained) but this is not what is being questioned about the models, rather the issue is whether the model hindcasts matching historical temperatures to some degree is evidence that they have correct physics, or is merely a result of modelers making the choices for inputs which will produce a reasonable result.

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.
