If δQ1 is the total energy consumed or accumulated in unit volume of the lower atmosphere per unit time and δQ2 is that which enters in or comes out of this space per unit time δQ1 should be equal to δQ2. δQ1 and δQ2 are calculated by the following equations, We calculated numerically these equations of the atmosphere using the data obtained at Tokyo observatory. We made sure that the 1st law of thermodynamics holds satisfactorily good in the atmosphere.

As an example of application of Takahasi's method of the determination of period and damping ratio of the irregular motion of an oscillating body, we made some investigations on the periodicity of the dates of freezing of Lake Suwa.In the first place the method was applied to each of four sections into which the whole period of records was divided and next to the whole interval.As we can thought that the curve which was obtaind by the method expresses free oscillation of the system, so that we calculated the period and the damping ratio from that curve. Besides this, other methods, such as partial means and the normal statistical method, namely the method of correlation, have also been tried, We obtained, as a conclusion of these analysis, that there exist 3 years and 33 years periodicity in the dates of freezing of Lake Suwa.
