摘要
使用 1 992年 1 0月 - 1 998年 1 2月连续 75个月、2 30个重复周期的 Topex/ Poseidon卫星高度计有效波高资料 ,对南北大西洋波高熵的空间分布特征和时间变化规律进行了研究 ,统计分析了大西洋波高熵的多年的空间分布特征和多年各月的时间变化规律。结果表明 ,大西洋波高熵呈现出中间低、南北高的马鞍形空间分布特征和明显季节变化的规律 ,与大西洋的平均有效波高。
The Topex/Poseidon satellite altimeter significant wave height (SWH) data from October 1992 to December 1998 were used to study the wave height entropy in the Atlantic Ocean, and the statistical analysis of spatial distributions and temporal variabilites of wave height entropy in the Atlantic Ocean was made. It is shown from the analysis results that the wave height entropy in the Atlantic Ocean shows a saddle distribution with low value in the equatorial area and high value in the northern and southern sea areas and obvious seasonal variabilities, and is consistent with the distributions and variabilities of mean SWH, wind speed and atmospheric activities in the Atlantic Ocean.
