click the blue words to correct the statement below.
air mass a was cooler and more humid than air mass b.

Explanation:

1. First, interpret the map: Air mass B (circled area) has low specific humidity (pale purple, ~6-8 g/kg), while the green area (implied Air mass A) has high specific humidity (16-24 g/kg).
2. In the Southern Hemisphere, lower latitudes (closer to 30°S) are warmer, higher latitudes (closer to 50°S) are cooler. Air mass B is at ~30-40°S, so it is warmer than a higher-latitude air mass A.
3. Correct the false descriptors: Air mass A is cooler than B, and less humid than B.

Answer:

Air mass A was cooler and less humid than air mass B.
