项目摘要
The time evolution of the surface gravity wave field will be studied by combining a comprehensive field program in the Bight of Abaco with a fully non-linear model. The investigation began with the development of a two-dimensional wave array to measure the evolution of the wave spectrum and the meteorological forcing by the wind. Secondly, a new approach was developed for treating the non-linear wave-wave interaction term to provide better resolution of the energy transport and a more efficient scheme for evaluating the effect of the interactions on wave evolution. The present effort consists of a pilot field program in the spring of 1989 to be followed by a full experiment one year later. On the modeling topic, an adjoint model necessary to optimize a systematic expansion of the unknown source terms will be constructed. %%% This project couples a field program to measure the response of the surface ocean wave field to meteorological forcing with an attempt to develop a model incorporating the physical processes. At present, a non-linear wave evolution model has been developed, but required either massive computational effort, or a truncation to an overly simplified representation. This effort examines an alternate representation to the non-linear terms, which, if successful, would permit an inversion of the data to better understand the physical processes at work producing the wave field. The subsequent effort would then lead to a predictive model of the surface wave field forced by meteorological variables available from satellite or other techniques.
阿巴科湾的一个综合场程序和一个完全非线性的模型将结合起来研究地表重力波场的时间演化。调查从开发一种二维波阵开始,以测量海浪频谱的演变和风对气象的强迫。其次,提出了一种处理非线性波-波相互作用项的新方法,为能量传输提供了更好的分辨率,并为评价波-波相互作用对波浪演化的影响提供了更有效的方案。目前的努力包括在之春进行田间试验,一年后进行全面试验。在建模主题上,将构建优化未知源项的系统展开所需的伴随模型。这个项目结合了一个现场程序来测量海面波场对气象强迫的响应,并试图开发一个包含物理过程的模型。目前,已发展了一个非线性波浪演化模型,但需要大量的计算工作,或者截断到过于简化的表示式。这项工作研究了非线性项的另一种表示法,如果成功,将允许对数据进行反演,以更好地理解产生波场的物理过程。随后的工作将导致建立由卫星或其他技术提供的气象变量所强迫的表面波场的预测模型。
