Verb (abbreviation for verb) desert climate

Distributed in Xinjiang basin and western Inner Mongolia. There is little annual precipitation. The temperature changes greatly, the temperature difference between day and night is large, the temperature is high during the day and low at night. Less precipitation and insufficient vegetation coverage. The sky is very clear and transparent.
