Atmospheric Thermodynamics and Vertical Stability

Mohamed Habib Ahmed ElKanzi

Abstract: There are three main types of processes in which be interested 1) Cooling or warming at constant pressure.2) Expansion or compression.3) Mixing. Vertical motion of air masses in the atmosphere are accompanied by changes in pressure. So there are adiabatic expansion with and without condensation condensation. when a region of the atmosphere is unstable, convection may ensue, with vertical ascents and compensating descents of air i. e vertical mixing as well as horizontal mixing so far, air can be forced to rise even in a stable atmosphere, so can be vertical stability, conditional and latent instability, potential or convective instability if the opposite happen, i. e that the humidity increases with height, the layer will become stable with lifting. it is the case of potential or convective stability.
