When I ask Google, I get that convection is dominant, but radiation is 'none negligible'. I can't get a number for the life of me.
For Deep Seek, it happily gives me a number.
Overall ratio (surface to stratosphere): Radiation accounts for about 80-85% of the heat transfer, while convection accounts for 15-20%.
Which is totally wrong. I'm trying to get a number, since I suspect it is less than 1%, but I give up for now.
ps. Google states that for the current measured lapse rate, it shows that convection is dominant. But it runs into so much warmie stuff, that it can't give a straight answer.
what would be the temperature lapse rate if radiation were the dominant heat loss mechanism
If radiation were the dominant heat loss mechanism in the atmosphere, we would expect a significantly different temperature lapse rate. Here's why:
Radiative Cooling: Radiation primarily involves the emission and absorption of electromagnetic radiation. In the absence of other significant heat transfer mechanisms, the atmosphere would cool primarily through the emission of infrared radiation to space.
Expected Lapse Rate: A purely radiative atmosphere would likely exhibit a much steeper temperature lapse rate than the observed average of 6.5 °C/km. This is because:
Surface Cooling: The Earth's surface would radiate heat directly to space, cooling rapidly.
Atmospheric Cooling: The lower atmosphere would also cool rapidly through radiative emissions, leading to a strong temperature gradient.
I had to trick it with this roundabout question.
ps. The measured Lapse Rate is the only solid thing in this whole Influencer Science thing. It is the reduction of temperature as you go up in a balloon. Weather balloons measure this all the time. It is firmly on the side of convection, but nobody will say radiation is insignificant, nor will they give a number.
ps. so we must conclude this is a giant Chinese trap to make us botch up all the physics, so they can roll right over us... Wait, we already screw up the physics!
