Abstract
Concerning the influence of motion of air on the temperature lapse rate, there have been known several relations, for example Margules' formula concerning vertical motion of air, Byers' formula for application to isentropic weight chart, and Neamtan's stability tendency, etc.
In this paper Margules' formula is derived in such a manner that it can be applied to motion in general, with sufficient approximation. Also, from Margules' equation Neamtan's stability tendency is derived. In the case of moist adiabatic change, it is shown that a formula analogous to Margules' can be derived.
Application to weight chart in the case of moist adiabatic change is discussed. Also some applications of Charney's equation are discussed.
