摘　　要：海洋风要素是海洋学和气象学的基本参数,也是影响飞行器和航行器航行性能的重要因素之一。简要概述了海洋风场的基本概念、风速的高度和时距特性、阵风谱和长期分布以及我国海面风场时空变换特征,阐述了海洋风场的准定常风、风切变、急流、大气紊流和随机风的典型数学模型以及风场数值模拟方法,着重分析了海洋风场建模仿真在飞行控制、飞行性能、落点精度等领域的应用研究进展。The sea wind element is the basic parameter of oceanography and aerography ,which also has important in‐fluence on fly performance of aerocraft and aircraft .The basic concept of sea wind field ,the height and time characteristic of wind speed ,the flurry chart and long‐term distributing ,and the space‐time switch characteristic are summarized briefly in this paper .The typical mathematic models of wind such as mean wind ,gust ,turbulence and random wind are introduced . The application of sea wind field modeling simulation in flying control ,flying performance ,and hit accuracy of aerocraft are analyzed in detail .
