Numerical value of heat transferred is positive when it is transferred into the system, thereby increasing the energy contained in the system. That is, if q is the heat transferred from the surroundings to the system, then q 0 means that net heat is transferred to the system so as to increase the energy of the system.

Entropy production has been calculated as a function of the coefficient of meridional heat transfer for two seasonal energy-balance climate models. Both models display extrema in entropy production at values of the coefficient appropriate to the present climate. Inclusion of time dependence in the models is found to be the essential feature for successful application of entropy extremization.
The general climatic or meteorological environment determines the local mass and heat-exchange processes at the glacier surface, and these in turn determine the net mass balance of the glacier. Changes in the net mass balance produce a dynamic response—that is, changes in the rate of ice flow. The dynamic response causes an advance or retreat of the terminus, which may produce lasting evidence of the change in the glacier margin.

In conduction, heat is transferred from a hot temperature location to a cold temperature location. The transfer of heat will continue as long as there is a difference in temperature between the two locations. Once the two locations have reached the same temperature, thermal equilibrium is established and the heat transfer stops.
