potential temperature

[pə′ten·chəl ′tem·prə·chər]
(thermodynamics)
The temperature that would be reached by a compressible fluid if it were adiabatically compressed or expanded to a standard pressure, usually 1 bar.

potential temperature

The temperature a parcel of dry air would have if brought adiabatically to a standard pressure level of 1,000 millibars.

Consequently, sustained SSTs and enthalpy flux in the river plume may have helped support warm, moist atmospheric boundary layer conditions (observed via increased equivalent potential temperature) and may have provided enough atmospheric instability to overcome moderate vertical wind shear and aid in these storms' intensification and RI in this region.
Listen to or read weather forecasts to stay abreast of potential temperature changes as well as the heat index.
In (1), g represents the gravitational acceleration; [[THETA].sub.20] represents the potential temperature at the height of 20 m; [[THETA].sub.10] represents the potential temperature at the height of 10 m; U20 represents the wind speed at the height of 20 m; and U10 represents the wind speed at the height of 10 m.
Potential temperature and potential density were calculated according to Bryden (5) and Millero and Poisson, (6) respectively.
The sustained temperature rise shown with increased rpm is much higher than any potential temperature gain from increasing backpressure.
Says Hatfield, "The Evolve system is cloud-based, and it will allow us to better maintain and track any potential temperature spikes for medications.
By "toasty" we mean perhaps -50 degrees C while the tropopause underneath is a frigid -80, which is a big difference considering things like potential temperature and adiabatic cooling.
The fleet is outfitted with sophisticated technology, including on-board temperature recorders and alarms to alert drivers of potential temperature excursions as well as a PolarTrack, an online portal linked to a satellite navigation system allowing customers to access real-time delivery status and temperature conditions of their products.
If the equation is integrated between two different levels, and the potential temperature is replaced by the actual temperature, we obtain:
