Diabatic and adiabatic
WebDiabatic processes refer to those in which heat exchange occurs due to radiative transfer or turbulence. Semi-diabatic processes involve a combination of diabatic and adiabatic processes, where the net heat exchange is zero, but there is a change in temperature due to the exchange of heat between different regions or layers of the atmosphere.

WebJan 18, 2024 · The tendencies in relative humidity due to these diabatic processes and due to adiabatic processes are presented and discussed in Section 3. Section 4 discusses the use of monthly mean quantities when higher time resolution is not available; it also investigates which stratiform cloud subprocesses are the dominant contributors to relative ... This present article is written from the viewpoint of macroscopic thermodynamics, and the word adiabatic is used in this article in the traditional way of thermodynamics, introduced by Rankine. It is pointed out in the present article that, for example, if a compression of a gas is rapid, then there is little time for heat transfer to occur, even when the gas is not adiabatically isolated by a definite wall. In this sense, a rapid compression of a gas is sometimes approximately or loosely said to …
