On the Graphical Solution of Cloud Formation over Frontal Sarface, Taking into Consideratin Mixing of Warm and Cold Airs

Abstract

To discuss more precisely cloud formation or precipitation caused by the ascending of warm air over cold air it would be required to introduce a new conception of mixing of warm and cold airs into the treatment of this problem.
In this case a frontal su_??_face will change its form with time by mixing of warm and cold airs, so that it would be diffcult to treat this problem mathematically. The principle of our calculation, however, lies in treating successively in turn the ascent of warm air over cold air and their mixing for each short time. Here surface of discontinuity shall be defined by the boundary where warm and cold airs are mixed equally.
The mixing of warm and cold airs and the change of distribution of heat and water vapour contents might be calculated by “the Graphical Solution of Eddy Diffusion” suggested before by the present author.
