摘　　要：使用Topex/Poseidon卫星高度计 1 992年 1 0月到 1 998年 1 2月连续 75个月 ,2 30个重复周期的有效波高资料对南北大西洋的波侯进行了研究 ,统计分析了大西洋有效波高的累年累年各月和累年各季的空间分布特征和时间变化规律。结果表明大西洋波高呈现中间低、南北高的马鞍形空间分布特征和明显季节变化的规律 。The statistical analysis was made on the significant wave height(SWH) in the Atlantic Ocean with data from Topex/Poseidon altimeter from October 1992 to December 1998. The research included the work on the temporal and spatial distribution of SWH for years in succession and every month, every season for years in succession in the Altantic Ocean. The results indicated that there were evident seasonal variation reles in the distribution of SWH in the Atlantic Ocean, and the spatial distribution characteristic showed a saddle type, in other words, the SWH value was low in the equator Atlantic Ocean area, but it was high in the southern and northern Atlantic Ocean area. The SWH values had good corresponding relationship to the climate distribution in the Atlantic Ocean.
