摘　　要：针对天气预报预警等气象业务发展对三维可视化实况观测资料产品的应用需求,通过数据融合、垂直线性和反距离加权插值等算法的优化调整,实现了雷达基本反射率、国家级自动气象站观测数据和探空资料的三维可视化,动态生成三类资料的三维图像产品。利用三维可视化产品进行个例分析表明,与二维平面显示相比,气象数据三维可视化产品可以使气象工作者更加直观了解气象要素的空间分布情况,尤其是三维雷达产品,通过不同高度的雷达图可以了解雷达回波在水平和垂直方向上分布情况,对于掌握降水回波的发生发展情况很有意义。The development of meteorological services,such as weather forecast and early warning,has a great need for the application of 3D visual live observation data products.To respond to these needs,through the optimization and adjustment of data fusion,vertical linear and inverse distance weighted interpolation algorithm,this paper achieved the 3D visualization of radar basic reflectivity,national automatic weather station observation and radiosonde data.In addition,3D image products of three types of data are generated dynamically.The case analysis of 3D visualization products shows that compared with the 2D graphic display,the 3D visualization products of meteorological data can allow meteorologists to understand the spatial distribution of meteorological elements more intuitively,especially the 3D radar products.The distribution of radar echoes in horizontal and vertical directions can be understood via radar maps of different heights,which is of great significance for learning the occurrence and development of precipitation echoes.
