Tropical monsoons, occasionally also known as tropical wet climates or tropical and trade-wind littoral climates, are found in regions where there is a complete seasonal reversal of winds. Given the fact that our understanding of physical processes behind the formation of tropical monsoons is very incomplete and only based on weather mean conditions measured or observed near the ground (i.e.: pressure, precipitations and wind fields), we want to make a contribution to a better description of physic processes behind complete seasonal reversal of easterly (or westerly) winds in regions where tropical monsoons are observed by using the impacts of thermoelastic properties of saturated water vapor on atmosphere passive convection. Our results are based on Mbanes’ fundamental relationship of Atmosphere dynamic balance which leads to ADB-model and appropriate plots of both troposphere general circulations’ cells and related easterly (or westerly) winds generated by Coriolis force near the surface of the earth
