What does convectional mean?
Convectional is a technical adjective relating to convection, the bulk movement of a fluid caused by differences in temperature. It can describe currents, circulation, rainfall, mixing, or other processes arising from this motion. In meteorology, convectional circulation involves air rising after being heated and sinking after cooling, while in oceanography convectional flow can result from warmer, less-dense water moving above cooler, denser water. The term is chiefly used in formal scientific and geographical writing and is less common than the broader adjective “convective.” Although convectional closely resembles conventional in spelling, the words belong to different families and have unrelated everyday meanings. Convection derives through Latin from a root meaning “to carry,” linking it with words such as vehicle and vector. Its specialized meaning and similarity to a much more familiar word make convectional useful to know, particularly in discussions of the atmosphere, oceans, and heat transfer.
adjectiveRelating to convection, especially the bulk movement of a fluid caused by differences in temperature; describing a process, current, or circulation driven by such movement.
- Relating to or caused by convection, especially the bulk movement of a fluid produced by differences in temperature.

"Warm surface water can drive convectional mixing through the deeper layers of the ocean."
Convectional may sound like conventional, but one describes heat-driven fluid movement while the other describes established custom.

Where does convectional come from?
The English adjective convectional was formed from convection with the suffix -al. The noun convection comes through Latin from convectio, meaning a bringing together or transport, ultimately associated with con- and the Latin verb vehere, “to carry.” The same root underlies cognates such as vehicle and vector, while convection and convective are closer English relatives of convectional.
How convectional is actually used
This is a formal and relatively uncommon technical term, used particularly in meteorology, oceanography, geophysics, and heat-transfer contexts. It is less common than “convective” and should not be confused with “conventional.”
Easily confused with convectional
Convectional relates to the movement of a fluid due to thermal differences, whereas conventional relates to established custom, practice, or accepted methods.
