Abstract:By using SST data from HadISST OI and a dataset of daily winter temperature from 92 stations in Northeast China,the relationships between Sea Surface Temperature Anomaly(SSTA) and winter air temperature in Northeast China have been studied using the Generalized Equilibrium Feedback Assessment (GEFA) method combined with the Empirical Orthogonal Function analysis (GEFA-EOF).The results show that among the five sub-basins in the tropical or northern hemisphere,winter air temperature anomaly are closely related to the synchronous SSTAs of Tropical Atlantic and North Atlantic,and have nothing to do with that of other basins.The negative and positive winter air temperature anomaly in Northeast China is strengthened by the positive-negative-positive three-pole mode of Tropical Atlantic SSTAs (TA3),and the positive-negative-positive three-pole mode of North Atlantic SSTAs (NA3),respectively,while the strengthening effect is more obvious in northern areas than in southern areas of Northeast China.The possible pathway can be explained as following,the TA3 mode stimulates the positive-negative-positive teleconnection wave train in the northern hemisphere,which results in the East Asia major trough moving to the Lake Baikal,thus facilitates the polar cold air moving south to Northeast China;while the direct response of NA3 mode of North Atlantic SSTAs weakens or even eliminates the East Asia major trough,which hinders the polar cold air from moving south and results in warm winter in Northeast China.
