摘要
利用TOPEX高度计风速资料，实现了对太平洋海面粗糙度（Zo）的计算。1997～1999年正是厄尔尼诺与拉尼娜事件发生时期，作者研究了1997～1999年Zo在ENSO期间的变化后发现：（1）EINion发生期间赤道附近翱最大值在A，C，B3个站点上移动；最小值在B，A2个站点上移动。（2）LiNina发生期间赤道附近2。最小值在A站点，最大值主要在B站点上。LiNina发生期间，1999年15个站点翱均大于正常年份和EINion发生期间的15个站点2。。（3）ENSO期间，四季Zo与正常年份相比都有显著改变。
We calculated values of roughness in 15 points using wind speed by TOPEX satellite Altimeter. We studied the changes of roughness during 1997-1999 （ENSO period） and compared them with roughness in 1996. We find some characteristics as follows： The largest roughness nearby equator is moving from station A to station C to station B and the smallest roughness is moving from station B to station A during the EI Nion period. The smallest roughness is in station A and the largest roughness is in station B during LI Nina period. The roughness of 15 stations in 1999 is bigger than those in 1996, 1997, 1998. The roughness of 4 seasons has prominent change during ENSO period when compared with 1996.
