摘要
本文利用WOA01(The World Ocean Atlas 2001)提供的多年平均1/4°×1/4°全球温、盐数据,根据地转方程,计算了20°S～70°N,100°～180°E西北太平洋区域的基态动力高度;利用AVIOSO(CNES)提供的Topex/Poseidon卫星高度计数据,计算并分析了ENSO现象较为明显的1997年西北太平洋动力高度及地转流的分布与变化情况。
This paper used the 1/4o×1/4o grids salinity and the temperature data of the WOA01 which is the average of many years, then the ground state dynamic height of the northwest pacific （20°S 70°N, 100°E 180°E） is calculated, and maps of sea surface dynamic height have been plotted. The Mercator 1/3° grids Topex/Poseidon sea surface height anamoly datas are used to analyse the distribution and transformation of grostrophic current of 1997, in which year the ENSO phenomenons is in evidence.
