In their recent paper on land and sea breezes, Dr. Kobayasi and Dr. Sasaki treated a theory on land and sea breezes in eminent manners. In the present paper, however, 1 have discussed the same problem without ignoring the factors due to the eddying motion. And the following results were obtained:-
1° Alternation of land and sea breezes as well as wind velocities and distribution of land and sea breezes. The velocity of land and sea breezes attained maximum at the seashore and is 7_??_8m/sec, at most.
2° The amplitude of the diurnal component of the barometric pressure variation is very large in the extensive land area, and very small on the sea. The difference of the variations at such two stations becomes 0.3_??_0.4mm Hg. approximately.
3° The approximate values for the coefficient of eddy diffusivity and the coefficient of eddy viscosity associated with land and sea breezes are concluded as about 105_??_106 C. G. S.
