The study looked at how precipitation in a desert area changed over time due to climate change. They found that overall, precipitation increased from 1973 to 2010, with more rain in spring, autumn, and winter, but less in summer. There were different patterns of increase and decrease in precipitation over different time periods. The researchers also discovered that temperature, sunshine, evaporation, and surface temperature all played a role in affecting the amount of rain. In summer, higher precipitation led to lower temperatures and less evaporation.
