  • Description:
    "The fact that the atmosphere is a mixture of gases and water vapor water is well-known. The role of water within the atmosphere is of course an essential component of the production of what we loosely term weather. One role of water vapor is to modify the density of the atmosphere gaseous mixture. The density is the fundamental variable relating geopotential and pressure increments for the hydrostatically balanced atmosphere. We have recently considered whether or not the role of water vapor within the thermodynamics and hydrostatic dynamics formulated for the global spectral model was strictly correct. In this note we review the current system of equations and recommend that certain adjustments be made to insure that the system of equations reflects the presence of water vapor to a high degree of accuracy"--Introduction.
