The border between stalled air masses is called a stationary front. This boundary separates two air masses with different characteristics, such as temperature and humidity, leading to prolonged periods of unsettled weather in the region.

The boundary between cold and warm air masses is called a front. Fronts can be stationary, moving, warm, or cold, and where they meet can result in weather changes such as precipitation and temperature shifts. The interaction of these air masses at a front is a key factor in determining local weather conditions.
Yes, a front is a boundary between two air masses with different temperature, humidity, and density characteristics. When these air masses meet, it can lead to changes in weather conditions, such as clouds, precipitation, and temperature shifts.
