The very slow Spring-time surface warming phenomenon confirms our thesis about the instant IR emission almost of the entire "absorbed" (not reflected) portion of the incident solar flux's energy. We have already explained why we put the word "absorbed" in brackets. We do it because the incident solar radiative energy, when interacting with the surface, does not get absorbed....
The radiative interaction with the surface is not similar to the blackbody Type 1 emission concept. The blackbody Type 1 emission concept has to do with a blackbody already being warm and emitting from a warm surface, the surface energy is constantly supplied from inner source, or from the previously accumulated amounts of energy...
For blackbody Type 2 the incident solar flux doesn't have to warm the surface first in order to emit after,,, The emission happens simultaneously on the instant, the same instant the reflection (specular and diffuse) occurs.
When interacting with the surface the incident solar flux is almost entirely gets pushed out, except for a very small portion, which is what accounts for a very slow by the surface heat accumulation during the Spring-time periods.
And it is very well known and observed fact, that at the time of summer solar Solstices (in mid of June) the conditions are not so much hot as in July, and July plus the first week of August are considered the warmest period of the year. In mid June the sun climbs at its highest position on the midday sky, on mid June the day is the longest, but, nevertheless, the temperatures are not the highest.
The surface has yet to warm more, because the small amount of energy which is provided for surface's heating continues to get accumulated and doesn't have reached its maximum in mid June.
There is still a lot more energy to be accumulated to reach the maximum summer temperatures... and it is a well known fact and a well known observation. This phenomenon occurs because the portion of the incident solar flux's energy to be accumulated is very small, compared to Solar flux's intensity and solar flux's long summer day implementations.
And, during the incident solar flux the transformed into the accumulated heat solar energy, should account not only on the IR emitted portion, but on the entire incident solar flux's energy - reflected SW (specular and diffuse) IR emitted and a very small portion transformed into heat and accumulated in the surfaces inner layers. (It is a suggestion - but the radiative energy flux cannot get engaged in an interaction by simply being totally reflected from the matter, and without leaving a least energetic "footprint". It is a materialistic suggestion - there is not a perfect, there is not "a non energy consuming" reflection process in NATURE, because there are not perfect processes...)
So, the developed on the surface's every infinitesimal "i" spot temperature Te.i does not account as the Te.i inducing a necessary temperature gradient between the solar flux and the receiving energy surface. The incident solar flux's-surface interaction cannot be considered as an analogous to a hot surface being put in contact with the colder one... The solar flux will only add some small amount of energy to a hotter surfaces, like the hot iron rod, which when solar irradiated becomes even hotter.

The analogue we can find in the thermal behavior of an electric resistance heated element. The element will continue to release energy, no matter how hot the environment is.
The released energy is proportional to the electrical current going thru the resistance and does not depend on the surrounding environment's temperature.
So, we can consider the small portion of the incident solar flux's energy as the surface's "resistance" to the energy hitting, or the energy transformation loss.
