海浪是影响舰船行进和结构设计的最核心的环境要素。海浪参数的统计分析是建立舰船环境适应性长期预测模型的基础。对1993-2011年沿海台站、浮标观测资料,高度计观测资料和船舶报观测资料进行双线性插值,给出了海浪波高的分析场。利用波高分析场对WAVEWATCHIII(WW3)模拟结果进行最优插值同化。给出了海浪统计玫瑰图、极端海浪统计参数和海浪累年二维极值海浪谱等与舰船耐波性有关的海浪统计参数,分析了中国近海的波浪特征。
Waves are the most important environmental elements that influence the design and operation of ships. The statistical analysis of wave parameters is the basis for establishing a long-term predictive model of ship environmental adaptability. Based on the bilinear interpolation of coastal station, buoy observation data, altimeter observation data and marine observation data from 1993 to 2011, the analysis field of wave height is given. WAVEWATCHIII (WW3) simulation results were optimized and interpolated using wave height analysis. The statistic parameters of the waves related to the ship surge resistance are given, such as the rose statistic rose chart, the extreme wave statistic parameter and the two-dimensional extreme wave spectrum of the wave year after year. The wave features of the offshore of China are also analyzed.
