摘要：

本文根据1950～1995年共46a的西北太平洋气象船舶报资料,按5°×5°网格统计的风、浪要素进行分析研究,阐明了西北太平洋风、浪、涌的特点及其变化规律.该区是世界最典型的季风气候区,季风时期的风向、浪向、涌向基本一致,赤道地区常年盛行东北浪。冬季季风比夏季季风强盛,相应的平均波高、大浪大涌频率也较大。该海域与北印度洋同属季风气候区,但其特点正好相反。本文为船舶在西北太平洋航行、作业和科学试验以及军事活动,提供了较翔实的风场和浪场资料及变化规律。

The meteorological data for shipping in the The western part of the N. Pacific Ocean during 1950~1995 analyzed taking 5°×5° latiude and longitude as staistical girds.The characteristics and changing laws of the wind, wave and swell are given. This area is representative’s monsoon area. In the period of monsoon, the directions of wind, wind wave and swell are roughly consistent. In a year, the direction of wind wave is almost Northeast in equatorial zone. The monsoon in winter is stronger than that one in summer,corresponding, the average wave high is higher, and the frequencies of rough sea and heavy swell are also stronger.Both of North Indian Ocean and this sea area is monsoon area, but characteristic is opposite. This text provide specification data of wind field and wave field and the changing law for ships sailing、 working、 scientist and military active in The western part of the N. Pacific Ocean.
