摘要： Outputs of control experiment and CO2-doubling experiment with GFDL-CM2.1 coupled model were used to evaluate the effect of CO2-doubling on changes in extreme precipitation in China. The result shows that CO2-doubling would cause a prominent increase in annual extreme precipitation amount and precipitation intensity in eastern China, and a prominent increase in annual extreme precipitation frequency in eastern China except the south part of North China. Furthermore, CO2-doubling would influence the distribution of extreme precipitation in spring and summer, leading to increases in the frequency, intensity and amount of extreme precipitation in most of eastern China. However, the annual precipitation in both the south part of North China and the mid-lower reaches of the Yangtze River would decrease, due to the reduction of the wet days in spring and summer as well as in light rain and moderate rain.
