摘要The spatiotemporal variability of equatorial Pacific upper ocean heat content (HC) and subsurface heat during two types of El Nio-Southern Oscillation (ENSO), namely eastern and central Pacific (EP and CP) types, is investigated using subsurface ocean heat budget analysis. Results show that HC tendencies during both types of ENSO are mainly controlled by oceanic heat advection beneath the mixed layer to the thermocline, and the role of net surface heat flux can be neglected. The most important three terms are the zonal and vertical advections of anomalous heat by climatological currents (QU (0) T', QW (0) T') and zonal advection of climatological heat by anomalous current (QU'T (0)). The large contribution of QU (0) T' extends from west to east along the equatorial Pacific. The considerable contribution of QU'T (0) is confined to the east of 160A degrees W, and that of the QW (0) T' is observed in the central Pacific between 180A degrees E and 120A degrees W. In particular, a major contribution of QW (0) T' is also observed in the far eastern Pacific east of 100A degrees W during EP ENSO. There is also a small contribution from meridional advection of climatological heat by anomalous current (QV'T (0)). In contrast, the meridional advection of anomalous heat by climatological currents (QV (0) T') and vertical advection of climatological heat by anomalous current (QW'T (0)) are two damping factors in the HC tendency, with the former dominating. Differences in spatial distribution of the heat advection associated with the two types of ENSO are also presented. We define a warm water heat index (WWH) as integrated heat content above 26 kg m(-3) potential density (26 sigma (E mu) ) isopycnal depth within 130A degrees E-80A degrees W and 5A degrees S-5A degrees N. Further examination suggests that the recharge-discharge of WWH is involved in both types of El Nio, though with some differences. First, it takes about 42 (55) months for the evolution of a recharge-discharge cycle during an EP (CP) ENSO. Second, the EP El Nio event peaks during the discharge phase, 7-8 months after the recharge time. The CP El Nio peaks during the recharge phase, 4-5 months before the recharge time. The locations of HC anomalies in the El Nio mature phase relative to those at recharged time explain why the EP and CP El Nio peak in different stages of the recharge-discharge process.
