What is a characteristic of maritime tropical air masses?

Maritime tropical air masses are characterized by their formation over warm tropical waters. This high temperature and moisture content contribute to the humid and warm air associated with these air masses. As they transition over land, they can influence weather patterns, often leading to warm and moist conditions. Their source over the ocean allows them to absorb significant amounts of moisture, which can result in precipitation when these air masses move inland or interact with other air masses.

The other characteristics do not apply to maritime tropical air masses, as they do not form over cold land areas, do not bring cool, dry air, and while they can be stable at times, they are not necessarily predictable in their movements and influences on weather.
