Morphology
The noun phrase is a straightforward adjective + noun composition: 'warm' (higher temperature) modifying 'front' (a meteorological boundary), so the combined meaning of a boundary of warmer air is directly derivable. This compositional pattern is common cross-linguistically (e.g. Spanish 'frente cálido', French 'front chaud') and would be predictable to a B1 learner who knows both constituents.
Etymology
Warm front uses warm and front to paint a simple picture: it is the place where warm air moves into colder air, like a warm wave pushing into a cold area. That's why it means a moving area of 'warmer air' that brings 'warmer weather' and often rain.
