利用全球海洋Argo网格数据集、SODA月平均海洋数据集和CCMP风场数据,通过EOF分析,揭示了阿拉伯海5、50、100、200 m层海温全年2次增温、2次降温的双峰变化特征.结果表明,5 m层温度变化双峰信号出现在第一模态,其方差贡献率为75.79%,该... 利用全球海洋Argo网格数据集、SODA月平均海洋数据集和CCMP风场数据,通过EOF分析,揭示了阿拉伯海5、50、100、200 m层海温全年2次增温、2次降温的双峰变化特征.结果表明,5 m层温度变化双峰信号出现在第一模态,其方差贡献率为75.79%,该信号主要受风场、太阳辐射及风生环流影响;50 m层温度变化双峰信号出现在第三模态,其方差贡献率为11.95%,该信号主要受风生环流影响;100 m层温度变化双峰信号出现在第一模态和第三模态,其中第一模态方差贡献率为52.03%,第三模态方差贡献率为9.55%.由100 m层第一模态可知,100 m层温度变化幅度最大、变化范围最广,是由于100 m层处于海洋温度变化最为剧烈的温跃层中.100 m层海温变化主要受风应力旋度(方向:向上为正)影响,风应力旋度为负时,大气对海洋的强迫导致局地海水辐合,温跃层加深,100 m层部分海域温度升高;风应力旋度为正时,大气对海洋的抽吸导致局地海水辐散,海洋深处的冷水上升,100 m层部分海域温度降低. 展开更多

The significant underestimation of sea surface temperature(SST)and the temperature in the upper ocean is one of common problems in present climate models.The influence of the wave-induced mixing on SST and the temperature in the upper ocean was examined based on a global climate model.The results from the model coupled with wave-induced mixing showed a significant improvement in the simulation of SST and the temperature in the upper ocean compared with those of the original model without wave effects.Although there has still a cold bias,the new simulation is much closer to the climatology,especially in the northern ocean and tropical ocean.This study indicates that some important physical processes in the accurate simulation of the ocean may be ignored in present climate models,and the wave-induced mixing is one of those factors.Thus,the wave-induced mixing(or the effect of surface waves)should be incorporated properly into climate models in order to simulate or forecast the ocean,then climate system,more accurately. 展开更多
