海洋响应模型对高质量风场的需求出现在对操作和极端气候的后报研究中，在沿海和海上结构设计中，以及在对海洋平台操作和船舶的预测中。海洋响应模型，如第三代（3G）波浪模型（WAM）和海洋气象局的3G波浪模型已经显示出很大的技能，在高质量的风场驱动下，在强热带和热带外系统中产生几乎完美的显着波高和峰值周期的后报。1990年10月美国东海岸事件的表面波动力学（SWADE）研究特别强度观测期（IOP）通过一个通用的波浪模型（WAM 3G）使用客观推导的和手绘的人工密集风场来放置几个风场。结果显示（Cardone等人，1995年），非常复杂的纯客观分析方案产生的一套后报显然被手绘运动学分析击败（图1）。不幸的是，这种人力密集，冗长的分析需要大约100个工时来产生10天的后报，这是一个明显不适用于长期后报研究和预测应用的时间框架。
The need for high-quality wind fields for ocean response models arises in hindcast studies of operational and extreme climate, in coastal and offshore structure design, and in forecasting for ocean platform operation and ships. Ocean response models such as the third generation (3G) wave model (WAM) and the Oceanweather’s 3G wave model have shown great skill in producing nearly perfect hindcasts of significant wave height and peak period in severe tropical and extratropical systems when driven by high quality wind fields. The Surface Wave Dynamics (SWADE) study special Intense Observational Period (IOP) of the October 1990 US East coast event put several wind fields using both objectively derived and handdrawn man-intensive wind fields through a common wave model (WAM 3G). The results show (Cardone et.al., 1995) that the suite of hindcasts produced by very sophisticated purely objective analysis schemes was clearly beaten by hand-drawn kinematic analysis (Figure 1). Unfortunately, this man-intensive, tediously produced analysis took approximately 100 manhours to produce a 10 day hindcast, which is a time frame clearly inapplicable to long term hindcast studies and forecasting applications.
