Answer to Question 1

Answer: Maritime tropical air masses have an enormous influence on the southeastern United States, especially during the summer. These air masses form over the Atlantic and the Gulf of Mexico and migrate into North America. As the air flows inland, heating from the warm surface increases the environmental lapse rate and makes the air even more unstable. The combination of high moisture content and increased instability favors the development of heavy but short-lived precipitation, often thunderstorms over relatively small areas.

Answer to Question 2

Answer: Yes, because Antarctica qualifies as an arctic source region.
