where QIS is the inversion strength (g x [kg.sup.-1] x [(50 hPa).sup.-1]), q is the specific humidity (g x [kg.sup.-1]), pmin is the height of the inversion top (hPa), and [p.sub.max] is the height of the inversion base (hPa).

Caption: Figure 6: The correlation between the vertical velocity (a, b), specific humidity (c, d), geopotential height (e, f), and IIBT ((a), (c), and (e) for 700 hPa; (b), (d), and (f) for 500 hPa) in winter half year.
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.
As viewed from the contrast in the specific humidity change curves detailed in Figure 3(c), the existence of Bosten Lake obviously altered the distribution and diurnal changes in the moisture above the Gobi Desert's lakeshore area.
(2011); Harwell (2012) Dalton/mass transfer/ Bulk aerodynamic E = f(u)([q.sub.0] - [q.sub.r]), where f(u) = m(u)+b Summary: Rate E is calculated from the difference in water vapor pressure or specific humidity at the water surface [q.sub.0] and the atmosphere at a given reference level [q.sub.r].
Specific humidity is defined as the mass of water vapor per unit mass of moist air in units of gram per kilogram (grain per pound).
In order to examine the impacts, we use the sounding data to validate the specific humidity and temperature simulation.
The shape and height of the evaporation duct was diagnosed by first computing high-resolution (1-m vertical spacing) Monin-Obukhov surface-layer profiles of temperature and specific humidity. These were obtained using the hourly forecasts of 10-m temperature and specific humidity, sea level pressure, and sea surface temperature.
