Potential Temperature - the temperature a parcel of dry air would have if brought adiabatically (i.e., without transfer of heat or mass) to a standard pressure level of 1000 mb ...
Potential temperature - A measure of heat. It is the temperature air would be if brought dry adiabatically to 1000 mb.

Potential temperature The temperature that a parcel of dry air would have if it were brought dry adiabatically from its original position to a pressure of 1000 mb.
POTENTIAL TEMPERATURE- The temperature of an air parcel after it is lowered or raised to the 1000 mb level.
PRECIPITATION (PCPN)- Solid or liquid water falling from the air (i.e. snow, sleet, rain, hail, etc.) ...
Equivalent Potential Temperature, typically expressed in degrees Kelvin, is directly related to the amount of heat present in an air parcel. Thus, it is useful in diagnosing atmospheric instability.
Same as Theta e.

equivalent potential temperature"(Also called wet-equivalent potential temperature.) A thermodynamic quantity, with its natural logarithm proportional to the entropy of moist air, that is conserved in a reversible moist adiabatic process.
EQUIVALENT POTENTIAL TEMPERATURE- The temperature of a parcel of air after all moisture and latent heat is condensed out of an air parcel then descended to the 1000 mb level. Also known as Theta-E ...
Virtual Potential TemperatureThe virtual potential temperature is the temperature a parcel at a specific pressure level and virtual temperature would have if it were lowered or raised to 1000 mb. This is defined by Poisson's equation.
Thermodynamic ChartA chart containing contours of pressure, temperature, moisture, and potential temperature, all drawn relative to each other such that basic thermodynamic laws are satisfied.
(An index of hydrological drought corresponding to levels below the mean in streams, lakes, and reservoirs.)Dry AdiabatA line of constant potential temperature on a thermodynamic chart.
(An index of hydrological drought corresponding to levels below the mean in streams, lakes, and reservoirs.)Dry AdiabatA line of constant potential temperature on a thermodynamic chart.
Examples are absolute humidity, equivalent potential temperature, radioactivity, and CCN composition. 2. Any substance in the atmosphere that can be used to track the history of an air mass. It can be chemical or radioactive in nature.
Theta-e Index (TEN) It represents the greatest decrease in equivalent potential temperature measured in a layer beginning at or below 700 mb.
THETA-E (or Equivalent Potential Temperature)
The temperature a parcel of air would have if a) it was lifted until it became saturated, b) all water vapor was condensed out, and c) it was returned adiabatically (i.e.
Although the word "inversion" implies that temperature increases with height, the word "capping inversion" is used more loosely for any stable layer (potential temperature increasing with height) at the top of the boundary layer.
In this analysis method, the forecaster looks at constant potential temperature (the temperature that it would take if we compressed or expanded it adiabatically to the pressure of 1000 mb) surfaces.
When particularly strong, with high potential temperatures that suppress small-scale convection in the layers beneath them, they are often termed capping inversion.
Isentropic Surface - A two-dimensional surface containing points of equal potential temperature.
Isobar - A line connecting points of equal pressure.
Isodrosotherm - A line connecting points of equal dew point temperature.
Isentropic Lift - Lifting of air that is traveling along an upward-sloping isentropic (line of equal potential temperature) surface. Situations involving isentropic lift often are characterized by widespread stratiform clouds and precipitation.
