In case you are posting under difference addresses, please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in a previous post. Thank you.

Here is my answer to another similar post.

Since this is not my area of expertise, I searched Google under the key words "heat convection" to get these possible sources:

I hope this helps. Thanks for asking.

The word you are looking for may be INSOLATION. (Note the spelling diffrence from "insulation").

It could also be just "radiation", one of the three forms of heat transfer -- along with convection and conduction.
