Moisture/Humidity » Saturation Mixing Ratio (ws) Skew-T Procedure

To find the saturation mixing ratio for a given temperature and pressure on a plotted sounding, read the value, either directly or by interpolation, of the saturation mixing-ratio line that crosses the T curve at that pressure.

In this example, a parcel of air at 850 hPa with a temperature of 5°C has a saturation mixing ratio of 6.5 g/kg.
