Abstract: The precipitation reduction in North China has made the already intense water resource situation evenmore severe, which poses a great threat to local industrial and agricultural production and future development,and has aroused great concern of the governments at all levels and the scientific community. For example, to alleviatethe situation of water stress in North China, the Central Government has implemented the South-to-NorthWater Diversion Project. What is the the mechanism for changes in North China precipitation? Understandingthe problem can help us to recognize the future trends and reverse time in precipitation of North China. Fromthe angle of interdecadal variations of precipitation in North China, this article mainly reviewed the impact mechanism on summer precipitation in North China on the sea surface temperature, the East Asian summer monsoon,subtropical high, snow and sea ice changes. Finally, thisp paper pointed out the direction for future research,including: what is the time for North China precipitation transformation from less to more; the mechanism of ENSO impact on precipitation in North China and the influence of ENSO long-term variation trend onprecipitation in North China; what is the impact mechanism of Indian Ocean sea surface temperature anomalieson summer precipitation in North China; how to better quantitatively describe the East Asian summer monsoon intraseasonal, interannual, decadal variations and their impact mechanism on summer rainfall in North China;subtropical high intraseasonal changes, long-term changes and how they affect summer precipitation in North China.
