摘　　要：利用ECMWF ERA-40再分析波浪数据,来计算波龄,无因次波高以及无因次周期。采用Toba3/2指数率的方式来研究无因次波高与无因次周期的关系。通过研究得出了无因次波高与无因次周期的变化规律,比较大洋东岸与西岸发现,大洋东岸无因次波高与无因次周期分布较集中;大洋东西岸无因次波高与无因次周期的关系比较接近。In this paper, ECMWF Re-analyses data is used to calculate the wave ages, the non-dimensional significant wave heights, non-dimensional wave periods. The relationships between the non-dimensional wave heights and non-dimensional wave periods were to study using the way of Toba threeseconds power law. The relationships between the non-dimenslonal wave heights and non-dimensional wave periods were obtained via the study. It was shown that distribution of the east coast of the dimen- sionless wave heights and periods were more concentrated, but distribution of the west coast of the dimensionless wave periods and wave ages were more concentrated. The relationships between the nondimensional wave heights and non-dimensional wave periods were very close in the east and west coast of the ocean.
