The comparison of the equivalent potential temperature of parcels of air at different pressures thus provides a measure of the instability of the column of air.

The occurrence of mafic dike swarms in Archean and Paleoproterozoic terrains is often cited as evidence for mantle plume activity associated with abnormally high mantle potential temperatures.
23.
:The melting point of gold ( ~ 1000 C ) is significantly lower than the potential temperature of a charcoal fire ( ~ 2700 C ).
24.
Suitable boundary conditions have to be imposed for the wind velocity components u, v and w, the potential temperature \ theta and pressure p at all boundaries.
25.
The air around the mountain is stable because the air at the top, due to its lower pressure, has a higher potential temperature than the warmer air below.
26.
Each of these coefficients are functions of the known variables, such as the average wind speed at 10m, and average potential temperature and moisture at the surface and 10m.
27.
These equations along with the ideal gas law are used to evolve the density, pressure, and potential temperature scalar fields and the velocity vector field of the atmosphere through time.
28.
Things like the temperature ( potential temperature ), precipitable water, and to an extent the pressure thickness simply move from one spot on the grid to another with the wind.
29.
Since potential temperature is conserved under adiabatic or isentropic air motions, in steady, adiabatic flow lines or surfaces of constant potential temperature act as streamlines or flow surfaces, respectively.
