In meteorology terms, which pairing defines a Maritime front?

• A. front between continental arctic air mass and maritime polar air mass.
• B. front between maritime polar air mass and continental polar air masses.
• C. front between mT and mA.
• D. front between maritime arctic air mass and maritime polar air mass.

Answer: (D)

Maritime front is the boundary where two air masses formed over the sea meet. When two maritime air masses interact, their contrast in temperature and moisture creates a distinct frontal zone. The pairing of maritime arctic and maritime polar air masses fits this idea precisely: both originate over the ocean, so their encounter is a maritime front, typically a cold-front-type boundary at high latitudes. The other options involve a continental air mass (not maritime) or mix types that don’t illustrate two maritime air masses meeting to form a maritime front. So this pairing clearly demonstrates the maritime-front concept.
