Explain the climatic controls that make the southern and northern desert regions of North America dry
What will be the ideal response?
ANSWER: The southern desert region of North America is dry because it is dominated by the subtropical high most of the year, and cyclonic winter storm systems tend to weaken before they move into the area. The northern region is in the rain shadow of the Sierra Nevada. These regions are deficient in precipitation all year long, with many stations receiving less than 13 cm (5 in.) of rain annually.?
