yes the idea was to model independent systems and then couple together for interaction , I wanted to start first with the heat transfer and balance of energy to determine the general heating and surface temperature, I yet have to implement differential types of emissivity for land , sea and in future ice too , to keep things simple, I didn't want to model 3dimensional verticality in atmosphere or in ocean depth , eventually I might add a a second layer of shallow water and deep water , butyet to be seen , mathlab is giving me headakes to make it work as I want and I am not understaiding yet how to fix the issue that the north emisphere doesnt get colder in winter and so warmer the southern emisphere, somethig is wrong .
