What occurs during a warm front?

During a warm front, a warm air mass is indeed overrunning a cooler air mass. This phenomenon occurs when the warm air, which is less dense, rises over the denser cold air. As the warm air ascends, it can lead to the formation of clouds and precipitation, typically characterized by gradual increases in temperature and humidity as the warm front approaches. This transition often results in extended periods of light to moderate rainfall, and the weather conditions change progressively.

The aspect of a warm air mass overrunning a retreating cold air mass captures the essence of how warm fronts function in weather patterns. As the warm front moves, it typically leads to a rise in the atmospheric temperature as well as a change in weather conditions, marking a shift from colder to warmer weather. This thermodynamic interaction is fundamental to understanding how warm fronts influence weather systems.
