The map below shows six source regions for different air masses that affect the weather of North America. The directions of movement of the air masses are shown. Using the standard two-letter air mass symbols from the Earth Science Reference Tables, label the air masses by dragging the correct symbol to each circle on the map.
Base your answer to the question on the map, which represents the geographic source regions of two air masses, X and Y. The arrows represent the convergence of these air masses, which may result in tornadoes. Identify the two-letter symbol for air mass X.
cP (continental Polar)
mT (maritime Tropical)
cT (continental Tropical)
mP (maritime Polar)
cA (continental Arctic)
