Abstract: The relationship between the preceding boreal winter Northern Hemisphere annular mode (NAM) and the spring extreme low temperature events in the north of eastern China during 1959-2008 was examined in this study. The results show that there exists a significantly negative relationship between the preceding winter (December-March) NAM and the following spring (March-May) extreme low temperature events in the north of eastern China. When the preceding winter NAM is strong, in the following springy negativc (positive) geopotential height anomalies occur in the upper (lower) levels over the north of eastern China, and anomalous sinking motion and vertical heating arc accompanied in the same area with the cold vortices over Northeast China being weak,resulting in less extreme low temperature event.The opposite circulation patterns in the springy arc obviously observed in weak preceding winter NAM years. Furthermore,the possible physical mechanism associated with the impact of the preceding winter NAM on the subsequent spring extreme low temperature events in the north of eastern China is explored. Thc results indicate that the Eurasian snow cover is a potential bridge connecting the signals in winter NAM and spring extreme low temperature events in the north of eastern China. When the preceding winter NAM is Strong (weak),warmer (colder) surface air temperature occurs over the mid-high latitudes of Eurasia and the Eurasian snow cover area is smaller (larger) than normal. Besides, Eurasian snow cover area anomalies in the preceding winter can strongly persist to the following spring. When the preceding winter Eurasian snow cover area is small.accordingly in the following spring cold vortices over Northeast China arc weak and the surface air temperature in the north of eastern China is higher, resulting in less extreme low temperature events, and vice vers.Thereforr.the preceding winter NAM contributes to the frequency and intensity of the following spring extreme low temperature in the north of eastern China, yielding a potential valuable signal in predicting spring extreme low temperature events in the above-mentioned region.
