## Entropy Flows in the EAS

Let us look at the simplified scheme ofthe energy flows in the EAS shown in Figure 1 (see Energy Flows in the Biosphere).

Space q(SG)

Figure 1 Energy flows in the EAS. SWR is the flow of short-wave radiation with TS = 5800 K, LWR is the flow of long-wave radiation with the temperatures of the Earth's surface (ground), TG = 288 K, or the atmosphere TE = 253 K; EVT is the flow of latent heat (evapotranspiration), and Turb + Frict is the flow of turbulent heat (sensible flow) + the flow of heat discharged in mechanical movements (friction).

SWR is the flow of short-wave radiation with TS = 5800 K, LWR is the flow of long-wave radiation with the temperatures of the Earth's surface (ground), TG = 288 K, or the atmosphere TE = 253 K; EVT is the flow of latent heat (evapotranspiration), and Turb + Frict is the flow of turbulent heat (sensible flow) + the flow of heat discharged in mechanical movements (friction).

Using Figure 1 we can write equations of entropic balance for the EAS (atmosphere + ground) in a more detailed way:

d-G_4 q(SG) qi(GA) ^(GA) 4 q(GS) di-o ~dT = 3 ~ TG 3 Tg + ~dT

--a = 4 q(SA) qi(GA) q2(GA) 4 q(AS) d,-A dt 3 Ts To To 3 Te dt

It is interesting that the exchange entropic flows, de-o/dt« — 0.586 WK" m— for the ground and de-A/dt0.576 WK— m— for the atmosphere, are almost equal, and their sum is equal to de-/dt— —1.16 W K—1 m—2, that almost coincides with the value given by eqn [2]. In accordance with Prigogine's theorem,

dt dt dt dt
