Air masses are classified based on their source region’s latitude (determining temperature: Equatorial (E), Tropical (T), Polar (P), Arctic/Antarctic (A)) and the surface type (determining moisture: Maritime (m) over oceans, Continental (c) over land). A Maritime Equatorial air mass forms over warm oceans in the equatorial region, making it warm and moist.

Air masses are classified by temperature (based on latitude of origin) and moisture content (based on surface type of origin). Maritime Equatorial (mE) air masses originate over warm equatorial oceans.

Let’s examine the other options:
B) Maritime Polar (mP): Forms over cold oceans in polar regions, typically cold and moist. The description “Warm oceans in the tropical zone” refers to mT (Maritime Tropical).
C) Continental Tropical (cT): Forms over warm land in the tropics, typically warm and dry. The description “Less warm oceans in the tropical zone” is incorrect.
D) Continental Polar (cP): Forms over cold land in polar regions, typically cold and dry. The description “Moist oceans in the polar zone” refers to mP (Maritime Polar).
Only option A accurately describes the characteristics and source region of a Maritime Equatorial air mass.
