A tale of shifting relations: East Asian summer and winter monsoon variability during the Holocene
Abstract Understanding the dynamics between the East Asian summer (EASM) and winter monsoon (EAWM) is needed to predict their variability under future global warming scenarios. Here, we investigate the relationship between EASM and EAWM as well as the mechanisms driving their variability during the...
