Abstract
In Part I the method of height computation on. the T log p-Diagram is studied, Among many possible forms of the height computation diagrams a simple and useful one is mentioned which is applicable as well to Herlofson's Skew T logp-Diagram. In Part II, which deals with the main subject of this report, the features to be possessed by the adiabatic diagrams are analysed and by means of the equal-area transformations of T log p-Diagram the forms of the adiabatic diagrams are studied, which satisfy these features. Tephigram, Aerogram and Tropogram are included as special cases of the results of the systematic study From among the possible diagrarfis suggested by this study a diagram, named “ log Θ, H-Diagram”, is presented, which is regarded as the simplest and most effective one.1.
