tropical air mass
Quick Summary
A tropical air mass originates in the tropics and is characterized by high temperatures and humidity. These air masses form when the atmosphere remains over a large, uniform surface, like the ocean, long enough to acquire its temperature and moisture properties. Tropical air masses are a significant source of moisture and are responsible for much of the year's rainfall.12
In meteorology, air masses are classified by their source regions. Tropical air masses are distinct from polar air masses, which form in higher latitudes and are cold. The interaction and mixing of polar and tropical air masses occur in the middle latitudes.23

- air mass
The maritime Tropical (mT) is the most important moisture-bearing and rain-producing air mass throughout the year. In winter it moves poleward and is cooled by the ground surface. Consequently, it is characterized by fog or low stratus or stratocumulus clouds, with drizzle and poor visibility. A steep lapse…

Warm, moist maritime tropical (mT) air forms over tropical and subtropical ocean waters in association with the high-pressure regions prominent there. Cool, moist maritime polar (mP) air, on the other hand, forms over the colder subpolar ocean waters just south and east of the large, winter oceanic low-pressure regions.…
