This paper gives a brief description of annual period and seasonal variation in the wave height field entropy in the northeastern Pacific. A calculation of the quantity of the

received by lithosphere systems in the northern hemisphere is introduced. The wave heat field entropy is compared with the difference in the quantity of the sun's radiation heat. Analysis on the transfer method

period and lag of this scasonal variation led to the conclusion that the annual period and seasonal variation in the entropy of the wave height field in the North-western Pacific is due to the seasonal variation of the sun's radiation heat. Furthermore

the inconsistency between thermodynamic entropy and information entropy was studied.
