摘要
引起全球海平面变化的因素是复杂多样的,大气压、风、大洋环流以及海水密度的变化,都会引起海平面在时间、空间上的变化,而海水温度的变化是海平面变化的主要原因。该文利用法国Ar- chiving,Validation and Interpretation of Satellite Oceanographic data(AVISO)的海表面高度异常数据,计算了1992年10月至2007年1月间,全球海平面的平均上升速度,同时详细解算海平面上升速度的全球空间分布,分析全球海平面的变化趋势并将海平面变化同美国国家海洋大气署(NOAA)的Optimum Interpolation Sea Surface Temperature(OISST)海表面温度数据进行了比对和相关分析。
There are many factors that cause the temporal and spacial change of the global sea level, such as the atmospheric pressure, wind, ocean current and seawater density. Among these factors, the sea surface temperature is the main source that changes the sea level. The global sea level rise from October 1993 to January 2007 is calculated based on the sea level anomalies data provided by the Archiving, Validation and Interpretation of Satellite Oceanographic data （AVISO）, and the spacial distribution of the sea level rise is also obtained. The correlation of the sea surface temperature and the sea level change is analyzed by comparing the Optimum Interpolation Sea Surface Temperature （OISST） data derived from National Oceanic and Atmospheric Administration （NOAA） with the sea level anomalies data.
