Yuma's precipitation occurs in two well defined seasons, winter and summer, with distinctly drier springs and autumns. The result is a double curve characterized by two periods of maximum precipitation and two periods of minimum. Because it is relatively close to the poleward margin of the subtropical desert, Yuma is influenced somewhat by the migrating frontal disturbances that commonly cross the more northerly portions of the United States in winter. This frontal precipitation results from maritime air from the Pacific overriding modified polar continental air from the interior of the continent.

Its summer is hot and long, with 38°C or above being recorded on one third of the days in the year and also on every day from June to early September. On one half of the days in the year, temperatures of over 32°C are recorded. 6°C. In July, the hottest month, the mean daily temperature is 33°C, the mean maximum is 41 °C, the mean minimum is 25°C, and the diurnal range is 16°. Yuma, on the Colorado River, is at an elevation of only 43 meters. Winter temperatures are mild, yet the daily range is great; in January, the coldest month, the mean daily temperature is 13°C, the mean maxi- 26 RICHARD F.

All of the air involved is extremely dry. In summer, on the other hand, the interior of Asia becomes very warm—the result of its massive bulk and its lack of moderating oceanic influences, combined with a large receipt of solar energy resulting from the long days at such high latitudes. This in turn induces the development of low pressure, which draws air in from all sides, creating the famous monsoon. But the great mountain arc that sweeps from the Caucasus eastward through the Hindu Kush and Himalayas to the Khingan and other ranges of China effectively prevents the moisture-laden air of the summer monsoon from penetrating into the interior of the continent.
