Mixing Ratio The mixing ratio is defined as the ratio of the mass of water vapor to the mass of dry air and is expressed in grams per gram or in grams per kilogram. Convert mixing ratio to specific humidity or vice-versa. Title: PrMet Thermo Diagrams - All v9.1 color Author: Roland Stull Created Date: 9/20/2015 4:09:23 PM For many purposes, the ~TildeLink() may be approximated by the specific humidity.M meterName applied to a class of instruments which measure the liquid content of the atmosphere. For mixing ratios, the contour interval is 2 g/kg and mixing ratios exceeding 16 g/kg are color-filled with dark green in order to indicate the areas that are quite moist. From the user, an air temperature , a dewpoint temperature , and a station pressure are given.. The flow of air at the isentropic surface is represented by streamlines, computed… The mixing ratio of a discrete blob of moist air does not change with varying atmospheric pressure and temperature as it moves in the atmosphere. The dewpoint can be measured directly by several kinds of dewpoint hygrometers or it can be deduced indirectly from psychrometers or devices that measure the water vapor density or ~TildeLink(). share | improve this question | follow | edited Mar 2 '18 at 13:13. kwinkunks.
