英文摘要 | Marine heatwaves (MHWs) have adverse impacts on marine ecosystems and fi sheries, yet extreme MHWs in the western tropical Pacific Ocean remain largely unexplored. Here, we investigate the evolution and drivers of the two strongest subsurface MHWs in the western tropical Pacific Ocean on record, in 2008 (MHW-08) and 2010-11 (MHW-11). The two events have similar evolutions, as they were both initiated and developed locally in tropical regions during their onset phase and gradually dissipated with multiple cores during the decay phase. We examined the physical processes during the evolution of MHW-08 and MHW-11 and performed a heat budget analysis for the subsurface layer in each case. We fi nd that the onset of both events were mainly controlled by convergence and vertical heat advection due to anomalous Ekman downwelling, while the decay of both events was mainly controlled by horizontal heat advection due to anomalous horizontal currents and withdrawal of anomalous convergence. The relationship between the subsurface MHWs and El Ni & ntilde;o-Southern Oscillation is discussed. We suggest that the anomalous heat advections plus the La Ni & ntilde;a-related background warming lead to the extreme subsurface MHW events. Our fi ndings may have important implications for environmental change and marine life in the western tropical Pacific Ocean. |
