中文摘要 | Using the high-resolution Hybrid Coordinate Ocean Model and the Navy Coupled Ocean Data Assimilation Global 1/12A degrees Analysis (GLBa0.08), and the Objectively Analyzed Air-Sea Fluxes and the International Satellite Climatology Cloud Project products, we investigated the seasonal and interannual evolutions of heat budget, including the pseudo-heat content change, the net air-sea heat flux and the eddy heat transport (EHT), based on the time-dependent heat budget analysis in the western Pacific warm pool (WPWP). The results show that the pseudo-heat content change has significant semi-annual variation, which peaks in April-May and September. There is strong positive feedback between EHT and the net air-sea heat flux. EHT is important in balancing the sea surface heat flux into the WPWP. The seasonal EHT variability is dominated by its meridional component. On the interannual time scale, the zonal and vertical components of EHT show comparable amplitudes with the meridional one. The observed net air-sea heat flux in the WPWP is highly correlated with EHT and the pseudo-heat content change on the interannual time scale. The net air-sea heat flux leads the pseudo-heat content change by about half a month and leads EHT by about one month. The variations of the air-sea heat flux and EHT are connected to the El Nio Southern Oscillation events: during the development of El Nio (La Nia) events, the warm pool expanded eastward (retreated westward), the net air-sea surface flux into the WPWP increased (decreased) and EHT enhanced (weakened) significantly. |
