以数学建模的方式对基于卫星云图的风矢场度量模型进行了研究。对卫星云图数据进行预处理分析,得到卫星云图数据的特征,结合卫星上传感器采集数据的过程,通过一些假设,建立了卫星-地球三维立体模型,结合半小时采样间隔的卫星云图数据,求解得到风矢场度量模型,通过三维绘图引擎编程对模型进行模拟实现。研究结果表明该模型可以很好的预测风矢场的变化趋势,计算高效,结果与实际相符,具有一定的实用价值。

Satellite cloud picture based wind vector field metrics model is researched by means of mathematical modeling.First,by preprocessing satellite cloud data,the satellite cloud data characteristics are genevated,then combining with the the process of gathering satellite sensors data,a satellite-Earth three-dimensional model is established with some assumptions.Combining with the the half-hour sampling interval data,the wind vector field metrics model is obtained,finally the model is simulated by a 3D graphics programing engine.The results show that the model can well predict the trend of the wind vector field,computationally efficiently,consistent with the reality.
