When the mT air mass moves over land, what weather does it tend to produce?

When the mT air mass moves over land, what weather does it tend to produce?

• A. Cool, Stable Weather
• B. Wet Weather
• C. Very Dry Weather
• D. Clear Skies

Answer: (B)

Maritime tropical air is warm and very moist because it forms over warm tropical seas. When this moist, warm air moves over land, daytime heating makes it rise more easily, increasing instability. As it rises, it cools and the water vapor condenses, forming clouds and often bringing rain or thunderstorms. The high moisture content means precipitation is common, so wet weather is the typical outcome. In contrast, dry, cool, or clear conditions come from air masses that are dry or more stable, which doesn’t describe mT air.
