| 摘要 | The interaction between the thermocline and mixed layer is a key process important to the El Nino-Southern Oscillation (ENSO) in the tropical Pacific climate system. Decadal changes in the relationships between the depth of 20 degrees C isotherm (D-20C) and the temperature of subsurface water entrained into the mixed layer (T-e) are analyzed using observed temperature data during the periods 1955-2003 in association with the 1976-77 climate shift. The thermocline in the western tropical Pacific is anomalously deep before the shift, but shallow after the shift. It is found that the relationship has undergone decadal change in the far western tropical Pacific (west of 160 degrees E). The effects of the decadal changes in the D-20C-T-e relationships on ENSO properties are further examined using an intermediate coupled model (ICM). It is demonstrated that ENSO properties are sensitive to the decadal changes in the D-20C-T-e relationship in the far western tropical Pacific. |
