The invention comprises a 3D meteorological radar display method. The method is characterized by comprising that A) data, of a PPI format, collected by a meteorological radar is obtained, the data ofthe PPI format is converted into data of a CAPPI format, and the data of the CAPPI format is stored; B) the data of the CAPPI format is scanned layer by layer, and maximal scanning values in three 3Ddirections are obtained and stored; and C) the maximal scanning values stored in the step B) establish a mapping texture via a 3D function library to obtain a 3D model of a meteorological chart, and the 3D model is displayed in a display device. The surface of a 3D object is display in a screen, resource consumption of a video card of a computer is reduced greatly, and aberration caused by perspective can be avoided. 本发明公开了种三维气象雷达显示方法，其特征在于，该方法包括：A.获取气象雷达采集的PPI格式数据，将PPI格式数据转换CAPPI格式数据并进行存储；B.对CAPPI数据进行逐层扫描，获取三个三维方向上面的最大扫描数值并存储；C.将步骤B中存储的最大扫描数值使用三维函数库建立起贴图纹理，得到气象图的三维模型，并将三维模型在显示装置上进行显示。本方法只显示个三维物体的表面在屏幕上，这样可以极大降低计算机显卡的资
