中文摘要：

采用1982-2012年NOAA最优插值海表温度（第二版）数据资料和NCEP/NCAR再分析海表气温数据资料，利用均方差分析法，分析海表温度和海表气温的年际变化特征。将31年数据按照ElNin~o/LaNin~a事件分为a，b，c3组，利用超前/滞后相关性分析法，将中低纬度海域海表温度异常（SSTA）与海表气温异常（SATA）做超前/滞后相关分析，得到每个格点SSTA与SATA之间相关性最显著的时间，从而确定SSTA与SATA之间的超前/滞后相关关系。研究结果表明：中纬度海域以SATA超前SSTA为主，SATA滞后SSTA主要分布在20。S-20。N的热带海域。SATA与SSTA超前/滞后天数统计结果均呈现双峰型分布，SATA超前峰值出现在10d左右，SATA滞后峰值出现-7d左右。ElNin~o/LaNin~a事件的出现，对海气超前/滞后相关关系具有一定影响。

英文摘要：

The spatial distribution and interannual variation of sea surface temperature and sea surface air temperature with the mean square deviation are analyzed by using the NOAA OI SST V2 high resolution dataset and the NCEP/NCAR daily reanalysis dataset for the period from 1 January 1982 to 31 December 2012. Based on the occurrence of El Nin~o/La Nin~a events, the data of 31 years are divided into three groups： a, b and c. By applying lead/lag correlation analysis on daily SSTA and SATA data series for the middle and low latitude sea area, the lead/lag relationships of each grid point between SSTA and SATA are obtained. The results show that SATA leads are mainly conspicuous at the middle latitude and lags are basically restricted in tropical areas of 20.S-20.N. The atmosphere-ocean lead/lag statistics of the three groups all share the similar bimodal structure that the peak value of SATA lead appears in 10 d and lag appears in-7 d. The discrepancy in the spatial structure also demonstrates that the occurrence of El Nin？o/La Nina event has a certain influence on the atmosphere-ocean lead/lag relationships.
