Background, aim, and scope The occurrence of severe persistent pluvials during the summer monsoon season is perhaps one of the most pressing climate concern that faces China today. However, few works have focused on understanding the occurrence of the severe persistent pluvials in China, although studies to date have revealed some severe persistent pluvials over the last thousand years. The proxy data show the most wet period occurring from 1330s to 1420s over eastern China during the last 1500 years. Here, we focus on pluvial occurring in this period to assess the possible role of the internal variability of the climate system in hydroclimate over eastern China. Materials and methods The role of the internal variability of the climate system in driving the pluvial over eastern China is assessed by using the model data and paleo-proxy records. Results Based on proxy data, one such pluvial have occurred from 1380 to 1429 during this wet period. The hydroclimatic pattern in global which suggested by proxy records during 1380 to 1429 AD highlight relate regionally coherent climate changes with pluvials over eastern China. Such hydroclimatic pattern indicates coherent shifts in large-scale hydroclimatic patterns during this eastern China pluvial era which is similar with the climate dynamics associated with the internal variability of the climate system. These internal variability include persistent La Nina-like conditions in the tropical Pacific, the cool phase of the Pacific Decadal Oscillation (PDO), the warm phase of the Atlantic Multidecadal Oscillation (AMO) and the positive North Atlantic Oscillation (NAO) index during this time.
