本文以5°×5°分辨率对1950 ~ 1995年北太平洋航运气象资料进行了分析，给出了北太平洋风浪和涌浪的特征和变化趋势。赤道地区的风浪几乎全年为东北方向。冬季海浪强度大，平均浪高高于夏季，冬季巨浪和大浪发生频率也高于夏季。北太平洋和北印度洋都属于季风区，但它们的特征彼此相反
The meteorological data for shipping in the north Pacific Ocean during 1950-1995 are analyzed with 5°×5° resolution, and the characteristics and variation trends of wind wave and swell are given. The wind wave in the equatorial zone is in northeast direction nearly the whole year. The sea wave is stronger and the corresponding averaged wave height is higher in winter than in summer, and the frequencies of rough sea and heavy swell in winter are also higher than in summer. The north Pacific Ocean and the north Indian Ocean all belong to monsoon area, but their characteristics are contrary to each other
