Climate Alarmist and the covid fearmongers are all the same people doing it for the same reasons. Exactly right.
Not gonna dignify that with an lol reply…but I did…
just happened upon it and thought it fit well 😁
Do clouds prevent frost with back-radiation?
I know emissions are not sent from the ground to the cloud and bounced back to the ground in an impossible heating loop…but…what do we know about a low-ish cloud? We know it can’t be less than zero degrees because if it were, then it would be snowing or hailing down on us.
A blanket of cloud, while not exactly heating anything, will radiate an above-freezing infrared glow, thereby putting a limit to night-time cooling and preventing a frost below.
So, in answer to my first question, a cloud could be said to prevent frost not with back-radiation, but with radiation, pure and simple. Mind you, I’ve been wrong before. If I am, please put me right.
I once gave a lift to two paragliders who had just landed after a 20 mile flight, and they told me that usually the temperature at the cloud base was the same as first thing in the morning at ground level.
@J Cuttance – there’s usually higher humidity, and more latent heat release, hence no frost. This is why misting your garden before night will prevent frost. It’s the latent heat release from water vapour. And yes, there’s less cooling with clouds present. Of course this isn’t the RGHE though.
“Nighttime radiation cooling is very dependent on atmospheric water vapor conditions from cloud cover and ambient relative humidity. Low humidity areas like desserts and high elevation locations can generate large temperature drops: “… temperature differences as large as 40ºC have been measured for thermally insulated approximate black bodies in the Altacama dessert in Chile” (Eriksson and Granqvist). However, even mild winds can overwhelm the cooling effects of radiation. Many radiation cooling studies have been carried out by the agriculture industry. Fruit crops and certain types of seedlings are vulnerable to this phenomenon, making it advantageous to study avoidance strategies like using protective coverings, wind machines, fog generators, etc.”

“Christopher Langan, a white Mexican-American, is generally considered to have the highest recorded IQ on earth – roughly around 195-210. He knows advanced maths, physics, philosophy, linguistics, has studied at Harvard and Cambridge – got his PhD there.
Guess what? He fully believes that 9/11 was a staged attack by US-Israeli authorities. He believes in the great replacement and the genocide of whites. He believes that there is global Jewish conspiring. He has put forth a philosophical – logical proof of god. He fully opposes the vax.”
Just read his Wikipedia page: https://en.wikipedia.org/wiki/Christopher_Langan
If the solar irradiance is 1366 W/M2 outside the earth’s atmosphere, how does matter in the Thermosphere attain temperatures in the thousands of degrees C ?
Non-ideal gas effects…plasma and ionization etc.
Here is a very useful published peer reviewed paper of a modelling study by John Leslie Nicol.
In this paper physicist John Leslie Nicol uses a 12-hour diurnal surface illumination model to study the partition of solar energy between a solid planetary surface and a radiatively transparent nitrogen atmosphere. No need in his study for the continuous 24-hour surface illumination with artificially weakened sunshine over the dark nighttime surface of the globe.

“From this we find that the mean temperature of the air at low levels of a few metres – generally 1.2–2 m above the surface of the soil – is more stable than that of the surface skin and in general significantly higher than the surface temperature.”
Confirms that convection warms the air during the day and that without the downward radiation from water vapour at that temperature there would be killing ground frosts every night.

Pablo,
What is critical for me is that Dr Nichol establishes daytime warming of transparent air by a convective mechanism. To do this he uses the correct solar beam intensity and so confirms Joseph’s work.

Very useful, thanks.
