| 英文摘要 | A super El Ni?o event occurred in the equatorial Pacific during 2015 – 2016, accompanied by considerable regional ecohydro-climatic variations within the Mindanao Dome(MD) upwelling system in the tropical western Pacific. Using timeseries of various oceanic data from 2013 to 2017, the variability of eco-hydro-climatic conditions response to the 2015/2016 super El Ni?o in the upper 300 m of the MD region are analyzed in this paper. Results showed that during the 2015/2016 super El Ni?o event, the upwelling in the MD region was greatly enhanced compared to those before and after this El Ni?o event. Upwelling Rossby waves and the massive loss of surface water in the western Pacific were suggested to be the main reasons for this enhanced upwelling. Decreased precipitation caused by changes in large-scale air-sea interaction led to the increased surface salinities. Changes in the structures of the thermohaline and nutrient distribution in deep waters contributed to the increased surface chlorophyll a, suggesting a positive effect of El Ni?o on surface carbon storage in the MD region. Based on the above analysis, the synopsis mechanism illustrating the eco-hydro-climatic changing processes over the MD upwelling system responding to the El Ni?o event was proposed. It highlights the prospect for the role played by El Ni?o in local eco-hydro-climatic effects, which has further profound implications for understanding the influence of the global climate changes on the ocean carbon cycle. |
