There is no specific technical term; warm, tepid, and room temperature would all be acceptable in general speech.

warm air
The warm air mass
A warm air mass rises over a cold air mass at a warm front because warm air is less dense than cold air. This results in the warm air mass being forced to rise and cool, leading to the formation of clouds and precipitation at the boundary of the two air masses.
When warm air pushes into cold air the result is a warm front.
Chinook is a warm air current

warm air mass and cold air mass
basically a nice warm and hot peace of air in scientific terminology
Diffusion
Occluded
The scientific term for when a mist appears on windows is "condensation." This phenomenon occurs when water vapor in the air cools and transforms into liquid water droplets on a cooler surface, such as a window. It typically happens when warm, moist air comes into contact with a cold surface, leading to a decrease in temperature and an increase in relative humidity.
Convection (the movement of warm air) and Radiation (electromagnetic dispersal of energy, mostly through infrared wavelengths in this case)
The cold air pushes under the warm air.
I pushes the warm air upwards.
