外文摘要：In the recent four decades, there were three record-breaking El Ni?o events: 1982/1983, 1997/1998, and 2015/2016 events. A double intertropical convergence zone (ITCZ) pattern distinctively emerges over the eastern Pacific Ocean during boreal spring. Based on reanalysis (ERA-Interim) during 1979-2018, this study examines how these three extreme El Ni?os modulate such double ITCZs. The 1982/1983 and 1997/1998 El Ni?os moved both northern and southern ITCZs equatorward to form an individual and broad equatorial ITCZ. In contrast, the regulation of 2015/2016 El Ni?o was unique with a strengthened southern ITCZ to form a symmetric double-ITCZ. The above differences can be attributed to the different meridional structures of sea surface temperatures (SSTs). For the 1982/1983 and 1997/1998 El Ni?os, there was a meridionally symmetric structure of SST warming with a maximum at the equator. While for 2015/2016 El Ni?o, there was a meridionally symmetric structure of SST warming with a minimum at the equator. ? 2021 by the authors. Licensee MDPI, Basel, Switzerland.
