Abstract: Composite analyses using reanalysis data indicate that the time-lag correlations between indices of stratospheric annular mode（NAM） at 10 h Pa and Northeast Asia surface air temperatures（SATs） are statistically significant. Negative/positive stratospheric NAM anomalies are followed by negative/positive SAT anomalies. The leading time of the maximum value of negative NAM indices at 10 h Pa to that of Northeast Asia SATs is 20 to 40 days, and the leading time of positive stratospheric NAM to SATs ... More
