| 摘 要： | 本文用能谱方法分析了黄海的海表面水温(SST)场的准周期变化。由分析结果清楚地看出,SST具有高频准周期变化:黄海北部以2.6—3.2,1.4—1.7,3.6—3.8和6.7个月的准周期为主;3.3—3.6,5,1.3—2.3及6.7个月在黄海南部占优势。同时,两个海域都有6.7和3.3年的明显的准周期变化。

| Abstract: | Quasi-periodic variations of the sea surface temperature (SST) field from Huanghai Sea are analysed by using the energy spectrum method. From the result, it is clear that there are high frequency quasi-periodic variations of the SST: the dominant quasi-periods of 2.6-3.2, 1.4-1.7, 3.6-3.8 and 6.7 months in the northern part of the Huanghai Sea; 3.3-3.6, 5, 1.3-2.3 and 6.7 months in the southern part of the Huanghai Sea. At the same time, there are obviously quasi-periodic variations of 6.7 and 3.3 years in both areas. |
