| 摘 要： | 为了更深了解北太平洋年代际尺度海气相互作用,本文通过对湍流热通量和SST的相关关系进行了研究。当热通量和SSTA正相关时,代表海洋影响大气,而当二者相关系数为负时,表示大气强迫海洋。将整个北太平洋SSTA求平均和把北太平洋分成3个区域求SSTA平均,分别对热通量和SST的关系进行研究。结果表明,北太平洋冬季年代际尺度上的海气相互作用主要表现为海洋强迫大气,而在日本附近海域以及北太平洋中东部,海洋对大气的强迫作用最明显,因此这两个区域是北太平洋冬季年代际尺度上海气相互作用的关键区。

| Abstract: | In order to better realize the air-sea interaction on multidecadal time scales in the North Pacific, the correlation relationship between turbulent heat flux and Sea Surface Temperature (SST) was investigated. When the correlation coefficient was positive, the ocean affects the atmosphere, while negative, the atmosphere exerts forcing on the ocean. Two different methods were used to investigate the correlation between two variables. The relationship between the heat flux and the SST was investigated not only by taking average Sea Surface Temperature Anomaly (SSTA) in the North Pacific as a whole, but by dividing the average SSTA into three areas. Results show that the ocean exerts forcing on atmosphere in most North Pacific area, especially near Japanese sea and in the central and eastern part of the North Pacific. These two areas are the keys to the air-sea interaction in the North Pacific on multidecadal time scales. |
