The temperature of a desert is also a defining and unique characteristic. Most deserts are warmer during the day than they are at night, and the difference in temperature is quite drastic. The average daytime temperature is 100Â°F, while at night the average temperature is 25Â°F. This large temperature difference is due to low amount of moisture in the desert air.
The desert population rises along with the demand for water. The water that animals once drank is being drilled and drained for industries, agriculture, and people. Global warming is melting the glaciers in the cold deserts to melt. Weather Cold deserts have short, moist, and quite warm summers with fairly long, cold winters. The average winter is -2 to 4Â° C and the average summer is 21-26Â° C. In the winter, a cold desert receives quite a bit of snow.
