From the numerical modeling results , it can be found that there is a clockwise gyre in the middle part of bohai sea , whether in wintertime or in summertime . in summer , the clockwise gyre corresponding to the high - temperature and low - density center in the middle bohai sea is mainly dominated by the density circulation . and in winter , it is mainly dominated by the wind stress curl 通过数值模拟结果发现，在渤海中部，无论冬季还是夏季，都存在一个顺时针的涡旋运动，夏季，对应于渤海中部的高温低密中心，其流场主体部分呈顺时渤海冬夏季环流特征及变异的初步研究针向旋转，这主要是密度环流占优的结果，而冬季的顺时针向的旋转，主要是海面风应力旋度影响的结果。
Zhoushan is sea area which fertility is tiptop in our country . sea surface wind is important factor of influencing contrail of excursion oil and culturist so investigating sea surface wind of zhoushan and setting up numerical forecast model which fits this sea area can offer tool for study sea wind in this area and let us has a mensurable acquaintance ship of effect degree of physics factors which effect sea surface wind in zhoushan sea area and acquaint oneself with physic process 而海面风是影响溢油油团漂移轨迹和养殖业的重要因素，因此，对舟山海域的海面风进行研究，建立适合此区域的数值预报模式，可为研究该区域海面风作用过程提供数值预报工具，使我们对近海区域海面风场作用中物理因子的影响程度有更定量的认识，并对物理过程和影响机制有更深刻地了解。
The fifth chapter sum up the article and view the work . the simulation results indicate : ( 1 ) exchanging of sea - air and force of dynamical and thermodynamic processes is very important to bring and maintain sea surface wind . shf is mostly energy sources and lhf is negative effect in some area 模拟结果充分表明： ( 1 )感热和潜热的海气交换和动量交换(摩擦作用)对于海面风的发展和维持起着重要作用，潜热加热是海面风中最主要的能源，感热通量在一武汉理工大学硕士学位论文定区域对海面风风场有负面影响。
The first chapter introduces the signification of working over zhoushan sea area sea surface wind and state - in - art and technical route . the second chapter explains the mesoscale atmosphere model - mm5v3 , remark the mode system and controlling equations and emphases introduce the upswing of every module in order to fit zhoushan sea area 因此第二章针对本论文的主要研究手段：中尺度大气数值模式mm5v3进行了评述，对本文所采用的模式系统，控制方程组进行了介绍，并重点穿插介绍为适合舟山海域海面风的研究，各模块所作的改进，为今后的具体应用提供研究基础。
Combine with the project " hf ground wave radar supervise sea status " of state 863 project , retrieving wind direction from hf radar doppler spectrum and the showing of wind field , current field , wave field are researched in this paper . the problem of how to represent the sea surface parameters by computer is concerned , too 本文结合863 - 818 - 01 - 02课题“高频地波雷达海洋环境监测技术” ，研究了由高频雷达海面回波提取风向信息和海面风场、浪场、流场信息的计算机表征方法及其数据传输反演和表征的若干问题。
Based on mom2 model , a 3 - dimentional prognostic baroclinic z - ordinate model was established to study the circulation of east china seas , considering the real topography , inflow and outflow on the open boundary , wind stress , temperature and salinity exchange on the sea surface . the results are consistent with observation 本文基于mom2建立了一个三维斜压预报模式，采用真实海底地形，利用东中国海海面风应力、温度和盐度作为海面定解条件，并考虑其与外海界面处水体交换及温盐通量，对东中国海的冬季斜压环流实施了数值模拟研究。
The terrain effect force wind ' s speed reducing and wind ' s direction turning to left with contrasting the experiments of numerical simulation the text analyses the structure and microcosmic character of sea wind in zhoushan maritime space and consanguineous connection between sea wind and action of dynamical and thermodynamic . the task gets the result of case a by using t213 datum of weather center and contrasts it with the actual sea wind . the task establish a foundation in order to use this mode in the environmental forecasting 通过数值模拟对比试验，分析了舟山海域海面风的结构和微观特征，以及海面风与动力作用(复杂地形)和热力作用(海陆热力差异)之间的密切关系。进一步利用国家气象中心提供的t213高分辨率预报场检验海面风风场的数值预报效果，最后将其结果与实际观测作比较，为将该模式投入环境(海流，海浪，风暴潮等)动力预报奠定基础。
