Which air mass type is characterized by being warm and moist?

The air mass type that is characterized by being warm and moist is referred to as maritime tropical, commonly abbreviated as mT. This type of air mass forms over warm oceanic regions, which provides the moisture content, while the tropical origin contributes to the warmth.

Maritime tropical air masses are typically associated with stable weather conditions, resulting in warm, humid air that can lead to the development of clouds and precipitation, especially when they move over cooler land areas. This can significantly affect local weather patterns, especially in coastal regions where mT air masses are common.

Understanding air mass types is crucial in meteorology, as they play a significant role in weather forecasting and the overall climate of an area.
