The energy with which water is held in soil; equivalent to the negative pressure to which water must be exposed to so that it is in hydraulic equilibrium, through a permeable membrane, with soil water.
Industry:Weather
An increase with height of the moisture content of air; specifically, the layer through which this increase occurs, or the altitude at which the increase begins. See inversion.
Industry:Weather
The weight percentage of water (with respect to dry weight) retained by an initially saturated 1-cm-thick soil sample after it has been subjected to a centrifugal force 1000 times the force of gravity for 30 minutes.
Industry:Weather
The development of an area in the boundary layer (e.g., often observed on surface or 850-mb charts) where moisture values become higher than in the surrounding region. Moisture pooling typically occurs in an area of low-level convergence during the warm (growing) season, and can have a significant effect on convection initiation and evolution.
Industry:Weather
The adjustment of observed precipitation in a storm by the ratio of the estimated probable maximum precipitable water over the basin under study to the actual precipitable water calculated for the particular storm. The procedure is one step in determining the probable maximum precipitation for design purposes.
Industry:Weather
On a thermodynamic diagram, an isopleth of equivalent potential temperature or pseudoequivalent potential temperature. Moist adiabats on most diagrams are drawn for the pseudoadiabatic process, in which liquid water is removed as soon as it is condensed.
Industry:Weather
In meteorology, a general term usually referring to the water vapor content of the atmosphere, or to the total water substance (gaseous, liquid, and solid) present in a given volume of air. In climatology, moisture refers more specifically to quantities of precipitation or to precipitation effectiveness. See humidity; see also soil moisture.
Industry:Weather
An adiabatic process for which the air is saturated and may contain liquid water. A distinction is made between the reversible process, in which total water is conserved, and the pseudoadiabatic or irreversible moist adiabatic process, in which liquid water is assumed to be removed as soon as it is condensed.

Industry:Weather
An extension or protrusion of moist air into a region of lower moisture content. Cloudiness and precipitation are closely related to moist tongues.
