Based on the sea surface temperture (SST) data of Hadley Center, the temperture data of 160 stations in China and the reanalysis data of NCEP/NCAR, the variability of the interannual of North Atlantic SST anomaly (SSTA) in autumn and its association with early winter temperture in China are studied by using a variety of statistical methods such as Empirical Orthogonal Function (EOF) and correlation analysis. The results suggest that the first mode of North Atlantic SST anomaly EOF in autumn is North Atlantic Horseshoe Pattern (NAH) with negative (positive) SST anomalies in southeastern Newfoundland, and positive (negative) SST anomalies in the subpolar, subtropical and eastern North Atlantic , which revealed 20.5% variance. The results show that there is a significant positive correlation between NAH SSTA in autumn and early winter temperture in most parts of China. Further analysis show that the NAH SSTA in autumn can persist until early winter. When the NAH SST is in a positive (negative) phase in autumn, the heating (cooling) of NAH SSTA over the subpolar and subtropical in early winter can cause divergence (convergence) in the upper troposphere, and stimulate the teleconnected wave train from the North Atlantic to the mid-high latitudes of East Asia, with the high-level converge (divergence) in China. As a result, through the sinking(rising) movement, the total cloud cover in the above area is reduced (increased), the shortwave radiation reaching the surface has increased (reduced), and the longwave radiation transmitted from the surface to the lower atmosphere has increased (reduced).Under the action of diabatic heating, the temperature in most areas of China is abnormally high (low). NCAR CAM5.3 was used to simulate the effects of the NAH SSTA on atmospheric circulation, radiative forcing and air temperature in early winter. The simulation results were basically consistent with the statistical analysis results of the observational data. This further confirms that the SST mode can affect the atmospheric circulation anomalies in East Asia by stimulating the teleconnected wave train, thereby affect the interannual variation of air temperature anomalies in China through the effect of diabatic heating.
