It was found that the average rate of entropy production by absorption of solar radiation 652.4 mW/m2 K corresponds to the planetary value of 561 mW/m2 K. The average rate of entropy production by moist convection 22.9 mW/m2 K is very close to the planetary value of 23 mW/m2 K. On the other hand, the average rate of entropy production by dry convection of 27.1 mW/m2 K is 10 times greater than the planetary value of about 2 mW/m2 K.
