为了满足船舶与海洋工程对波侯数据的需要,本文回顾了以往出版的几种图集资料并分析了其不足之处,着重介绍了当前国际上较新的英国波峰综合模式(NMIMET)和美国海军风浪后报模式(SOWM)及两者的结果图集。为获得中国海与西北太平洋海域更可靠的数据,在对日本气象厅的器测浮标站长期资料的统计结果与相应的船舶报资料按各种方法处理的结果比较基础上,进一步改进了NMIMET模式。这主要是在波高与周期联合概率分布导算方法上,采用一种新的更灵活的联合分布模式以代替原来所用的由Ochi建议的二维对数正态模式;同时对于在模式中需要确定的有关周期的参数,根据新的资料和计算结果对原用的回归公式作出了改进。用改进后的模式导算得到的波高、周期分布与器测浮标站结果更为接近。
In order to meet the need of ship and marine engineering for the data of Bohou, this paper reviews several published data of some atlas and analyzes its shortcomings. It mainly introduces the current international newer peak integrated mode (NMIMET) and the United States Naval Storm Mode (SOWM) and the resulting set of both. In order to obtain more reliable data of China sea and Northwest Pacific Ocean, based on the comparison of the long-term data of the Japan Meteorological Agency’s measured buoy station with the corresponding results of ship data processing by various methods, the NMIMET mode is further improved . This mainly uses a new and more flexible joint distribution model instead of the original two-dimensional logarithmic normal mode proposed by Ochi in the method of joint probability distribution of wave height and period. At the same time, Of the parameters of the cycle, based on new data and calculation results of the original regression formula has been improved. The wave height obtained with the improved model is closer to the measured buoy station results.
