利用Topex/Poseidon卫星高度计1992年10月到1998年12月连续75个月 ,230个重复周期的有效波高资料对南北大西洋的波高成分进行了分析 ,结果显示频数密度峰值对应的波高成分因子在夏季为1 .4左右,冬季为1 .2左右 ,其他季节为1 .3左右。7 ,8 ,9月份大西洋含涌浪的波高成分占频数密度累积率的比例约为90 %左右 ,其中涌浪成分占优约为65 %左右 ;其余各月占85 %左右 ,其中涌浪成分占优约为60 %左右 ,表明大西洋海域常年有涌浪场存在 Based on the effective wave height data of Topex / Poseidon satellite from October 1992 to December 1998 for 75 consecutive months and 230 repetitive cycles, the wave components in the North and South Atlantic Ocean were analyzed. The results showed that the wave height component factor corresponding to the peak of frequency density was in summer About 1.4, winter is about 1.2, the other seasons is about 1.3. In July, August and September, the ratio of wave-height component to frequency-cumulative rate in the Atlantic Ocean was about 90%, of which the surge component accounted for about 65%, while the remaining months accounted for about 85%. The surge component About 60% dominated, indicating that the Atlantic Ocean there are all year round surge field
