It's when air in a region is very moist (humidity is high)
Humidity is typically low in a continental polar air mass because this air mass originates from high latitudes where the air is cold and dry.
A continental tropical air mass typically has low humidity and high air temperature. This air mass forms over hot and dry regions, such as deserts, and brings warm and dry conditions when it moves into different areas.
Maritime polar air masses originate over cold oceanic regions, which keep the air mass relatively cold. The air mass picks up moisture as it travels over the water, leading to higher humidity levels.
A continental tropical air mass originating from the desert regions of northern Mexico and the southwestern United States typically causes hot, clear, and dry summer weather in the U.S. This air mass brings high temperatures and low humidity, leading to the development of heatwaves and drought conditions.

An air mass with high humidity has picked up water by evaporation as the wind crosses over the oceans - hence the term maritime.
The temperature and humidity in the air mass remain relatively constant. This indicates that there is no significant change in weather conditions and the air mass is stable.
A continental tropical (cT) air mass is associated with low relative humidity and high air temperature. This air mass originates over hot, dry land areas and brings warm, dry conditions when it moves into a region.
Yes a low air pressure mass has more humidity.
The specific humidity formula is: Specific Humidity Mass of Water Vapor / Total Mass of Air
The humidity become higher.
Within an air mass, temperature, humidity, and pressure can vary depending on the air mass's source region. For example, a tropical maritime air mass will typically have warm temperatures and high humidity, while a polar continental air mass will have colder temperatures and lower humidity. Pressure will generally be higher in cooler air masses and lower in warmer air masses.
A continental tropical air mass typically has low humidity and high air temperature. These air masses form over dry, hot land areas and can bring warm and dry weather conditions when they move into new regions.
The humidity become higher.
