Abstract
When a basin-wide flood occurred in the flood season of 2020, there was the largest peak flow since the construction of the Three Gorges Reservoir in the upper reaches, while in the middle and lower reaches, the water level of the lower reaches of Jianli was in the forefront of history, and some stations continued to exceed the warning level for more than 40 days. In this paper, for the Yangtze River Basin in the summer of 2020, the rainfall characteristics are analyzed, and the causes of the abnormal flood-causing rainfalls are studied from the perspectives of the planetary-scale circulation characteristics (such as the subtropical high over western Pacific, the blocking high in the middle and high latitudes of Eurasia, and the summer monsoon in South Asia) and the classification of the low-level jet.
