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

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.
The two kittens sleeping by the furnace vent are primarily relying on convection for heat transfer. Convection occurs when warm air rises from the vent, circulating around the kittens and providing them with warmth. Additionally, some radiant heat from the vent may also contribute, but convection is the dominant mechanism in this scenario.
