Quizplus · Accepted Answer

The central United States is influenced by air masses from various directions. However, the most common air masses affecting the region are continental polar (cP) and maritime tropical (mT) air masses. cP air masses bring cold and dry air from northern Canada, while mT air masses are warm and humid coming from the Gulf of Mexico. These two air masses frequently collide in the central United States, leading to the formation of severe weather including thunderstorms, tornadoes, and snowstorms. Therefore, option A is the best choice.
