北仑附近海域海浪基本要素的统计分析

对北仑山海洋站连续观测6年的波浪资料进行了统计、分析，结果表明，本区波高小于0．5m的浪为常见浪，波高在0．5m和1．5m之间的出现频率，冬季最大，为19．5％，波高在1．5m和3．0m之间的出现频率，各季几乎相等，且都很小，为0．4％～0．5％，波高大于3．0m的出现频率为零．多年按月统计最大波高在1月，为2．5m，7月最小，为0．9m；波浪总特征表现为冬季较强，秋季次之，夏季最弱，波浪特征值，在宁波北仑海域海洋工程建设中具有重要价值。

Statistical Analyses of Essential Factors of Wave Near Beilun Sea Area

Statistical analyses are made on the wave data collected continually on the Ocean Station at Beilun Mountain during the period of 6 years. The results show that higher waves occurred mainly in winter, the maximum wave height is 2.5m in January and the minimum wave height is 0.9m in July. The general characteristics of the wave height show that the waves are highest in the winter, second in autumn and smallest in summer. These essential actors of wave shown in the tables are of great value to marine engineering construction of Beilun.
