A mass of extremely cold, dry air moves over the ocean. Which type of air mass does it most likely become?

Answer 1

When a mass of extremely cold, dry air moves over the ocean, it is likely to become warmer and more humid. This transformation occurs because the cold air mass will pick up moisture from the ocean's surface, leading to an increase in humidity. Consequently, the air mass may be classified as a maritime polar (mP) air mass if it retains some of its cold characteristics but becomes more humid. If it warms significantly and retains high humidity, it may transition into a maritime tropical (mT) air mass, depending on the temperature of the ocean water and the extent of the warming. However, initially, it is best described as maritime polar as it originates from its cold, dry state.
