Abstract:Using the monthly temperature from 81 stations of Jiangxi and the sea surface temperature (SST) data from NOAA, the possible relation between winter (DJF) temperature anomalies in Jiangxi and Global SSTA is analyzed. The coupling relationship between the anomalous distribution in winter air temperature and the variations of SST is studied with the Singular Value Decomposition (SVD) analysis method. The interaction between key areas is also discussed with the lead lag correlation analysis and SVD methods. The main results are as follows: (1) The winter air the temperature anomaly of Jiangxi had obviously identical distribution with concurrent SSTs over the Indian Ocean (10°S to 20°N, 54° to 90°E) and Northwest Pacific Ocean key area (20° to 40°N, 120° to 180°E), and the preceding August to September SSTs over the North Atlantic Ocean key area (24° to 44°N, 20° to 60°W); (2) The correlation between the warmer seawater and warmer winter in Jiangxi was better over the Northwest Pacific Ocean key area than that over the Indian Ocean, and the correlation between cooler seawater and cooler winter in Jiangxi was better over the Pacific Ocean than that over the Northwest Pacific Ocean. The SSTAs over the Indian Ocean and Northwest Pacific Ocean key areas can be used to correct the influence of the North Atlantic Ocean SSTA in winter air temperature prediction in Jiangxi.
