Relationship between cold winters over Northern Asia and the subsequent hot summers over mid-lower reaches of the Yangtze River valley under global warming

Under global warming, cold winters over Northern Asia are highly correlated with the subsequent hot summers over middle and lower reaches of the Yangtze River valley (MLYRV). This high correlation may result from an oceanic bridge's effect in the Western Pacific. The mechanism may be described as follows: the atmospheric circulation anomalies of cold winters corresponds with a simultaneous warmer Western Pacific warm pool (WPWP) by decreasing surface latent heat fluxes. The warmer sea surface temperature (SST) can persist and move eastward gradually to the subsequent summer through the oceanic processes, and thus in turn affect the hot days (HDs) over MLYRV.
