海水含盐量变化可预测厄尔尼诺现象美国科学家研究发现,观测太平洋海水含盐量变化,可以提前一年预测厄尔尼诺现象。美国马里兰大学的科学家分析了1980年至1995年间太平洋海水的数据,研究海水含盐量与厄尔尼诺现象的关系。科学家说,赤道两边较冷、含盐量较高的海水下沉,然后西部温暖、含盐量低的海水向东扩散,引起厄尔尼诺现象。美国宇航局计划于2006年至2007年间发射观测全球海水含盐量的卫星,这将有助于更好地预测厄尔尼诺现象。摘自2003.2.10《南湖晚报》
Changes in salinity of seawater can predict El Niño US scientists study found that observing changes in the salinity of the Pacific seawater can predict El Niño a year earlier. Scientists at the University of Maryland analyzed data on the Pacific Ocean water from 1980 to 1995 and studied the relationship between salinity and El Niño. Scientists say the colder, salty seawater sinks on both sides of the equator, and then the warm, salty seawater westward is spreading eastward, causing El Nino. NASA is planning to launch a satellite that measures global seawater salinity between 2006 and 2007, which will help to better predict El Niño. From 2003.2.10 “South Lake Evening News”
