A significant Madden–Julian oscillation (MJO) activity in the 2016 summer is observed with three MJO episodes corresponding to three stages of rainfall in China. The transition of the rainfall pattern is closely related to the propagation of the MJO. The atmospheric circulation linked to the anomalous rainfall can be modulated by the anomalous MJO convection through exciting a Rossby wave train and thus leading to the variability of the western Pacific subtropical high.
