(meteorology)
In a system of moist air, the (dimensionless) ratio of the mass of water vapor to the total mass of the system.

specific humidity

The weight of water vapor per unit weight of moist air (e.g., grams of water vapor per kilogram of air).

By means of a mixed-layer model, we study how different surface forcing influences the evolution of the boundary layer depth and the mixed-layer values of the potential temperature and specific humidity.
The first two terms on the right-hand side of Equation 15 correspond to absolute or specific humidity of incoming air, and the third term corresponds to outgoing supply air humidity.
State equation for specific humidity of supply air:
The interpretation of the absolutely unstable regime III is that for very large negative specific humidity gradients the mean virtual potential temperature will decrease with height.
Specific humidity anomalies are observed in the midtroposphere, below the strongest temperature anomalies.
Abushakra (2001) showed the advantage of including four driving variables in the hourly modeling of the energy use: (1) outdoor temperature, (2) outdoor specific humidity potential, (3) lighting and receptacles, and (4) occupancy.
