ElNino事件期间 ,全球的海洋和大气都会出现大范围的异常变化 ,1 997年初开始了一次强ElNino事件 .利用TOPEX卫星的高精度海洋测高数据可以观测到这次ElNino期间海面高度的变化 ,并为研究ElNino的形成和发展机制以及对全球气候影响提供参考 .
During the El Nino event, a wide range of anomalous changes occurred in the oceans and the atmosphere throughout the world, beginning with a strong El Niño event in early 1997. The changes in sea level during the El Niño period were observed using high-precision sea-altimeter data from the TOPEX satellite It provides a reference for studying the formation and development mechanism of ElNino and its impact on global climate.
