1. The geographical distribution of the diurnal component a1 of daily barometric change is compared with the distribution of land and water, a quantity called "continentality" being introduced which is the percentage of land in a definite area surrounding each station. 2. A linear relation between the amplitude and the continentality was assumed and a systematic discrepancy was discovered. 3. An elementary theory based on a number of simplifying assumptions is proposed and applied to actual examples. 4. The variation of the amplitudes and phases as functions of longitude could be explained in its essential features. 5. The inversion of phase near the pole is explained. 6. The minimum of amplitude near coast is pointed out and explained. 7. The influence of geographical conditions on the seasonal variation of amplitude is discussed and different possibilities pointed out. 8. A method of investigating the complicated variety of the seasonal variation under the light of the above theory is suggested, referring to some examples.
