黑潮延伸体区海平面异常和中尺度涡的时空特征分析OA北大核心CSTPCD
Spatial and temporal variability of the sea level anomalies and mesoscale eddies in the region of the Kuroshio Extension
利用1993-2010年间的卫星高度计资料,用EOF方法及小波分析研究了黑潮延伸体区域的海平面异常和中尺度涡的时空变化特征.研究结果表明:海平面EOF第一模态是季节模态,与该海域风应力旋度第一模态类似,相关系数达0.65.EOF第二模态主要反映了黑潮南部次级环流的变化情况,显著性周期是8-10年.通过相关分析发现黑潮延伸体南部次级环流的年代际变化与PDO有关,同时它又与风应力旋度第二模态有关；该海域的海面高度受到北太平洋东部SSH信号西传的影响,…查看全部>>
Based on the satellite altimeter data from 1993 to 2010, the temporal and spatial variations of the sea level anomalies and mesoscale eddies in the region of the Kuroshio Extension has been studied by EOF and wavelet spectrums analysis. The result of EOF analysis is as following: the first EOF mode of the sea level is a seasonal mode, which indicates that it tends to increase in the total region. Compared to the first EOF mode of the wind stress curl, it is …查看全部>>
