adiabat
- noun
- /ˈeɪdiəˌbæt/
- Specialized
- In thermodynamics, the dry adiabat shows how temperature changes without heat exchange in the atmosphere.
Examples
-
The texts I've seen all suggest that convection is required to establish the dry adiabat lapse rate. e.g. 39;12210;TOOLONG ... page 13.

Namely, it has to do with the fact that the lapse rate in the tropical atmosphere is basically expected to be pegged to the moist adiabat.

Under such conditions, convection is suppressed and the dry adiabat temperature profile cannot be established.

During the experiment, we plotted the adiabat to illustrate the temperature drop in a closed system.
-
To analyze the system's behavior, we drew the adiabat on the thermodynamic diagram, reflecting no heat transfer.

Etymology
Adiabat comes from Greek parts a- meaning 'not' and diabatos meaning 'passable', which is like the English word 'pass'. So an adiabat is a path where heat does not 'pass' — a process with no heat exchange.
