Which weather is typically associated with maritime tropical (mT) air masses?

• A. Heat and dryness
• B. Humidity and rain
• C. Cool and dry
• D. Cool and moist

Answer: (B)

Maritime tropical air masses form over warm tropical oceans, so they carry a lot of moisture and are warm. That combination means the air is humid to start with, and when it rises or cools, the moisture condenses into clouds and precipitation. So the weather they bring is humidity and rain. This stands in contrast to cooler, drier air from other mass types or to cool, moist air from colder oceans. The warmth plus high moisture content of mT air explains why rain and muggy conditions are the typical signature.
