# The Planet Surface Rotational Warming Phenomenon

### The Planet Surface SPECIFIC HEAT "Cp" Warming PHENOMENON

I’ll try here in few simple sentences explain the very essence of how the planet surface SPECIFIC HEAT "cp"warming Phenomenon occurs.

Lets consider two identical planets "H" and "L" at the same distance from the sun. Let’s assume the planet "H" has a Higher average surface specific heat, and the planet "L" has a Lower average surface specific heat.

Both planets "H" and "L" get the same intensity solar flux on their sunlit hemispheres. Consequently both planets receive the same exactly amount of SOLAR RADIATIVE ENERGY.

Depending on the specific heat capacity of bodies containing the heat energy, the temperatures can be quite different.

For Lower average surface specific heat planet "L" the sunlit hemisphere surface gets warmed at higher temperatures than for Higher average surface specific heat planet "H" the sunlit hemisphere.

The surfaces emit at σT⁴ intensity – it is the Stefan-Boltzmann emission law.

Thus the planet "L" emits more intensively from the sunlit hemisphere than the planet "H".

So there is MORE ENERGY LEFT for the planet "H" to accumulate then. That is what makes for Higher surface specific heat planet "H" to be a WARMER PLANET.

That is how the Planet Surface SPECIFIC HEAT "cp" Warming PHENOMENON occurs.

Yes, and thank you. So once L cools to planet H temperature, it continues to emit more radiation, even when it is cooler.

IR emission = σTΛ4.
Planet LTday =200K, LTnight =100K
To balance the same energy in = out
Planet HTnight grows higher (100+7,5) K, than HTday goes down (200-1) K.
So the HTmean > LTmean

Important - Rough example:

LTday>HTday
LTday - HTday = 20 oC

But
HTnight - LTnight = 50 oC

So HTmean>LTmean

Thanks

Important topic H on average is always warmer than L because L lit surface emits more intense24/7
For L Tmean=(Tnight+Tday)/2
For H the Tnight↑↑→T↑mean ←T↓day
(Tnight↑↑+T↓day)/2>(Tnight+Tday)/2 Thanks

Once the warmer planet L emitted adequet radiation to reach the same T as planet H, would not any further emissions then be equal?

Yes, and thank you. Just trying to understand. I should have specified planet L as sunlight side being warmer. Can you be more specific as to your answer. Once planet L cools to planet H temperatur

Thank you for asking. The planet L is not the warmer planet on average. The planet L is warmer on the sunlit side. The L is on average colder, because during the day it has already emitted more.
