| 英文摘要 | On the basis of maps of sea level anomalies data set from october 1992 to january 2004, pronounced low frequency variations with periods of about 500 d are detected in the area near 20 degrees n from 160 degrees w to 130 degrees e. a linear two-layer model is employed to explain the mechanism. it is found that the first-mode long baroclinic rossby waves at 20 degrees n in the northwest pacific propagate westward in the form of free waves at a speed of about 10.3 cm/s. this confirms that the observed low frequency variabilities appear as baroclinic rossby waves. it further shows that these low frequency variabilities around 20 degrees n in the northwest pacific can potentially be predicted with a lead up to 900 d. |
