Hi, Only if there is no propulsive force such as a fan pushing the air. If the force is gravity then yes, it would be convective.
Radiation warming
conduction
convection
Infrared heating uses electromagnetic waves to directly heat objects, while convection heating relies on the circulation of air to transfer heat. Infrared heating is more efficient and heats up quickly, while convection heating is slower but provides more even heating throughout a space.

conduction, convection, and radiation
it uses natural convection
The heating alone is not, no, but the convection it sets up, thus forming winds and weather systems, is a valid example.
