| 英文摘要 | During 2013-2020, the northern tropical Pacific Ocean (NTPO, 5 degrees N-20 degrees N) experienced a persistent surface warming of over 0.5 degrees C. This warming was accompanied by a consecutively low surface chlorophyll (SChl). Here, we combined observations with ocean general circulation model experiments to determine how the interplays between the North Pacific meridional mode (NPMM) and multi-year El Nino events jointly led to this persistent surface warming. The warm phase of NPMM (+) excited an anticyclonic circulation in the NTPO, which caused surface warming and enhanced the upper-ocean stratification in the western sector (160 degrees E-150 degrees W) and also deepened the thermocline in the eastern sector (150 degrees W-110 degrees W), resulting in a widespread decline in SChl. The NPMM (+) also triggered El Nino events during the subsequent winter, further decreasing the negative SChl anomalies by weakening the surface ocean current. Subsequently, two persistent El Nino events happened in succession (2014-2016 and 2018-2020), which acted to accelerate the decline in SChl by 2020. These results help to illustrate the effects of extratropical-tropical interactions on the compound physical-biological extremes under the global warming scenario. |
